+Generally, no clear opinions exist as to the usefulness of mental work
+in order to acquire a good technique.  We do not seem to know exactly
+what it means or how to develop technique through "brain work."
+Technique, when playing an instrument, means controlling the fingers.
+Generally, it is used only in a limited sense regarding fluency, rapid
+execution of difficult passages and steady aim.
+In order to acquire a perfect technique through brain work, an exact
+impression of the note picture upon the mind is the first problem which
+we must solve.  Thereafter we should busy ourselves with the study in
+question, as to fingering, touch, note value, etc., to achieve
+perfection along these lines in the broadest sense.  This occurs
+quickest and completely through intensive concentration of all
+intellectual powers and is, therefore, strenuous brain work.

+
+In order to attain a natural manner of playing the piano, that is to
+say, with the least possible strain and exertion, it is of the utmost
+importance to learn to exert the muscles consciously, and, what is of
+still greater importance, to relax them consciously.  My manner of
+accomplishing this differs from that of many other pedagogues.  I
+contrive to raise a feeling of relaxation from within, as it were. This
+is generally attempted by the aid of visible movements.  All superfluous
+movements are injurious.  The aim should be the very least possible
+strain of the muscles when playing the piano.

+Avoid worry and distractions of any kind when you are practicing.  Your
+mind must be every minute on what you are doing, or the value of your
+practice is lessened enormously.  By intense concentration, love of your
+work and the spirit in which you approach it, you can do more in a half
+hour than in an hour spent purposelessly.  Do not think you have been
+practicing, if you have played a single note with your mind on anything
+else.

+=head1 NAME
+
+perl5360delta - what is new for perl v5.36.0
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.34.0 release and the 5.36.0
+release.
+
+=head1 Core Enhancements
+
+=head2 C<use v5.36>
+
+As always, C<use v5.36> turns on the feature bundle for that version of Perl.
+
+The 5.36 bundle enables the C<signatures> feature.  Introduced in Perl version
+5.20.0, and modified several times since, the subroutine signatures feature is
+now no longer considered experimental. It is now considered a stable language
+feature and no longer prints a warning.
+
+    use v5.36;
+
+    sub add ($x, $y) {
+      return $x + $y;
+    }
+
+Despite this, certain elements of signatured subroutines remain experimental;
+see below.
+
+The 5.36 bundle enables the C<isa> feature.  Introduced in Perl version 5.32.0,
+this operator has remained unchanged since then. The operator is now considered
+a stable language feature.  For more detail see L<perlop/Class Instance
+Operator>.
+
+The 5.36 bundle also I<disables> the features C<indirect>, and
+C<multidimensional>.  These will forbid, respectively: the use of "indirect"
+method calls (like C<$x = new Class;>); the use of a list expression as a hash
+key to simulate sparse multidimensional arrays.  The specifics of these changes
+can be found in L<feature>, but the short version is: this is a bit like having
+more C<use strict> turned on, disabling features that cause more trouble than
+they're worth.
+
+Furthermore, C<use v5.36> will also enable warnings as if you'd written C<use
+warnings>.
+
+Finally, with this release, the experimental C<switch> feature, present in
+every feature bundle since they were introduced in v5.10, has been removed from
+the v5.36 bundle.  If you want to use it (against our advice), you'll have to
+enable it explicitly.
+
+=head2 -g command-line flag
+
+A new command-line flag, -g, is available. It is a simpler alias for -0777.
+
+For more information, see L<perlrun/-g>.

+=head2 Unicode 14.0 is supported
+
+See L<https://www.unicode.org/versions/Unicode14.0.0/> for details.
+
+=head2 regex sets are no longer considered experimental
+
+Prior to this release, the regex sets feature (officially named
+"Extended Bracketed Character Classes") was considered experimental.
+Introduced in Perl version 5.18.0, and modified several times since,
+this is now considered a stable language feature and its use no longer
+prints a warning.  See L<perlrecharclass/Extended Bracketed Character
+Classes>.
+
+=head2 Variable length lookbehind is mostly no longer considered experimental
+
+Prior to this release, any form of variable length lookbehind was
+considered experimental. With this release the experimental status has
+been reduced to cover only lookbehind that contains capturing parenthesis.
+This is because it is not clear if
+
+    "aaz"=~/(?=z)(?<=(a|aa))/
+
+should match and leave $1 equaling "a" or "aa". Currently it will match
+the longest possible alternative, "aa". While we are confident that the overall
+construct will now match only when it should, we are not confident that we
+will keep the current "longest match" behavior.
+
+=head2 SIGFPE no longer deferred
+
+Floating-point exceptions are now delivered immediately, in the same way
+as other "fault"-like signals such as SIGSEGV. This means one has at
+least a chance to catch such a signal with a C<$SIG{FPE}> handler, e.g.
+so that C<die> can report the line in perl that triggered it.
+
+=head2 Stable boolean tracking
+
+The "true" and "false" boolean values, often accessed by constructions like
+C<!!0> and C<!!1>, as well as being returned from many core functions and
+operators, now remember their boolean nature even through assignment into
+variables. The new function C<is_bool()> in L<builtin> can check whether
+a value has boolean nature.
+
+This is likely to be useful when interoperating with other languages or
+data-type serialisation, among other places.
+
+=head2 iterating over multiple values at a time (experimental)
+
+You can now iterate over multiple values at a time by specifying a list of
+lexicals within parentheses. For example,
+
+    for my ($key, $value) (%hash) { ... }
+    for my ($left, $right, $gripping) (@moties) { ... }
+
+Prior to perl v5.36, attempting to specify a list after C<for my> was a syntax
+error.
+
+This feature is currently experimental and will cause a warning of category
+C<experimental::for_list>.  For more detail see L<perlsyn/Compound Statements>.
+See also L</builtin::indexed> in this document, which is a handy companion to
+n-at-a-time foreach.
+
+=head2 builtin functions (experimental)
+
+A new core module L<builtin> has been added, which provides documentation for
+new always-present functions that are built into the interpreter.
+
+    say "Reference type of arrays is ", builtin::reftype([]);
+
+It also provides a lexical import mechanism for providing short name versions
+of these functions.
+
+    use builtin 'reftype';
+    say "Reference type of arrays is ", reftype([]);
+
+This builtin function mechanism and the functions it provides are all
+currently B<experimental>.  We expect that C<builtin> itself will cease to be
+experimental in the near future, but that individual functions in it may become
+stable on an ongoing basis.  Other functions will be added to C<builtin> over
+time.
+
+For details, see L<builtin>, but here's a summary of builtin functions in
+v5.36:
+
+=over 4
+
+=item builtin::trim
+
+This function treats its argument as a string, returning the result of removing
+all white space at its beginning and ending.
+
+=item builtin::indexed
+
+This function returns a list twice as big as its argument list, where each item
+is preceded by its index within that list. This is primarily useful for using
+the new C<foreach> syntax with multiple iterator variables to iterate over an
+array or list, while also tracking the index of each item:
+
+    use builtin 'indexed';
+
+    foreach my ($index, $val) (indexed @array) {
+        ...
+    }
+
+=item builtin::true, builtin::false, builtin::is_bool
+
+C<true> and C<false> return boolean true and false values.  Perl is still perl,
+and doesn't have strict typing of booleans, but these values will be known to
+have been created as booleans.  C<is_bool> will tell you whether a value was
+known to have been created as a boolean.
+
+=item builtin::weaken, builtin::unweaken, builtin::is_weak
+
+These functions will, respectively: weaken a reference; strengthen a reference;
+and return whether a reference is weak.  (A weak reference is not counted for
+garbage collection purposes.  See L<perlref>.)  These can take the place of
+some similar routines in L<Scalar::Util>.
+
+=item builtin::blessed, builtin::refaddr, builtin::reftype
+
+These functions provide more data about references (or non-references,
+actually!) and can take the place of similar routines found in L<Scalar::Util>.
+
+=item builtin::ceil, builtin::floor
+
+C<ceil> returns the smallest integer greater than or equal to its argument.
+C<floor> returns the largest integer less than or equal to its argument.  These
+can take the place of similar routines found in L<POSIX>.
+
+=back
+
+=head2 C<defer> blocks (experimental)
+
+This release adds support for C<defer> blocks, which are blocks of code
+prefixed by the C<defer> modifier. They provide a section of code which runs
+at a later time, during scope exit.
+
+In brief, when a C<defer> block is reached at runtime, its body is set aside to
+be run when the enclosing scope is exited.  It is unlike a UNITCHECK (among
+other reasons) in that if the block I<containing> the C<defer> block is exited
+before the block is reached, it will not be run.
+
+C<defer> blocks can be used to take the place of "scope guard" objects where an
+object is passed a code block to be run by its destructor.
+
+For more information, see L<perlsyn/"defer blocks">.
+
+=head2 try/catch can now have a C<finally> block (experimental)
+
+The experimental C<try>/C<catch> syntax has been extended to support an
+optional third block introduced by the C<finally> keyword.
+
+    try {
+        attempt();
+        print "Success\n";
+    }
+    catch ($e) {
+        print "Failure\n";
+    }
+    finally {
+        print "This happens regardless\n";
+    }
+
+This provides code which runs at the end of the C<try>/C<catch> construct,
+even if aborted by an exception or control-flow keyword. They are similar
+to C<defer> blocks.
+
+For more information, see L<perlsyn/"Try Catch Exception Handling">.
+
+=head2 non-ASCII delimiters for quote-like operators (experimental)
+
+Perl traditionally has allowed just four pairs of string/pattern
+delimiters: S<C<( )>> S<C<{ }>> S<C<[ ]>> and S<C<< < > >>>, all in the
+ASCII range.  Unicode has hundreds more possibilities, and using this
+feature enables many of them.  When enabled, you can say S<C<qr« »>> for
+example, or S<C<use utf8; q𝄃string𝄂>>.  See L<feature/The
+'extra_paired_delimiters' feature> for details.
+
+=head2 @_ is now experimental within signatured subs
+
+Even though subroutine signatures are now stable, use of the legacy arguments
+array (C<@_>) with a subroutine that has a signature I<remains> experimental,
+with its own warning category.  Silencing the C<experimental::signatures>
+warning category is not sufficient to dismiss this.  The new warning is emitted
+with the category name C<experimental::args_array_with_signatures>.
+
+Any subroutine that has a signature and tries to make use of the defaults
+argument array or an element thereof (C<@_> or C<$_[INDEX]>), either
+explicitly or implicitly (such as C<shift> or C<pop> with no argument) will
+provoke a warning at compile-time:
+
+    use v5.36;
+
+    sub f ($x, $y = 123) {
+      say "The first argument is $_[0]";
+    }
+
+Z<>
+
+    Use of @_ in array element with signatured subroutine is experimental
+    at file.pl line 4.
+
+The behaviour of code which attempts to do this is no longer specified, and
+may be subject to change in a future version.
+
+=head1 Incompatible Changes
+
+=head2 A physically empty sort is now a compile-time error
+
+    @a = sort @empty; # unaffected
+    @a = sort;        # now a compile-time error
+    @a = sort ();     # also a compile-time error
+
+A bare sort used to be a weird way to create an empty list; now it croaks
+at compile time. This change is intended to free up some of the syntax space
+for possible future enhancements to C<sort>.
+
+=head1 Deprecations
+
+=head2 C<use VERSION> (where VERSION is below v5.11) after C<use v5.11> is deprecated
+
+When in the scope of C<use v5.11> or later, a C<use vX> line where I<X> is
+lower than v5.11 will now issue a warning:
+
+    Downgrading a use VERSION declaration to below v5.11 is deprecated
+
+For example:
+
+    use v5.14;
+    say "The say statement is permitted";
+    use v5.8;                               # This will print a warning
+    print "We must use print\n";
+
+This is because the Perl team plans to change the behavior in this case.  Since
+Perl v5.12 (and parts of v5.11), strict is enabled I<unless it had previously
+been disabled>.  In other words:
+
+    no strict;
+    use v5.12;  # will not enable strict, because "no strict" preceded it
+    $x = 1;     # permitted, despite no "my" declaration
+
+In the future, this behavior will be eliminated and C<use VERSION> will
+I<always> enable strict for versions v5.12 and later.
+
+Code which wishes to mix versions in this manner should use lexical scoping
+with block syntax to ensure that the differently versioned regions remain
+lexically isolated.
+
+    {
+        use v5.14;
+        say "The say statement is permitted";
+    }
+
+    {
+        use v5.8;                           # No warning is emitted
+        print "We must use print\n";
+    }
+
+Of course, this is probably not something you ever need to do!  If the first
+block compiles, it means you're using perl v5.14.0 or later.
+
+=head1 Performance Enhancements
+
+=over 4
+
+=item *
+
+We now probe for compiler support for C11 thread local storage, and where
+available use this for "implicit context" for XS extensions making API calls for
+a threaded Perl build.  This requires fewer function calls at the C level than
+POSIX thread specific storage. We continue to use the the pthreads approach if
+the C11 approach is not available.
+
+F<Configure> run with the defaults will build an unthreaded Perl (which is
+slightly faster), but most operating systems ship a threaded Perl.
+
+=item *
+
+Perl can now be configured to no longer allocate keys for large hashes
+from the shared string table.
+
+The same internal datatype (C<PVHV>) is used for all of
+
+=over 4
+
+=item *
+
+Symbol tables
+
+=item *
+
+Objects (by default)
+
+=item *
+
+Associative arrays
+
+=back
+
+The shared string table was originally added to improve performance for blessed
+hashes used as objects, because every object instance has the same keys, so it
+is an optimisation to share memory between them. It also makes sense for symbol
+tables, where derived classes will have the same keys (typically method names),
+and the OP trees built for method calls can also share memory. The shared
+string table behaves roughly like a cache for hash keys.
+
+But for hashes actually used as associative arrays - mapping keys to values -
+typically the keys are not re-used in other hashes. For example, "seen" hashes
+are keyed by object IDs (or addresses), and logically these keys won't repeat
+in other hashes.
+
+Storing these "used just once" keys in the shared string table increases CPU
+and RAM use for no gain. For such keys the shared string table behaves as a
+cache with a 0% hit rate. Storing all the keys there increases the total size
+of the shared string table, as well as increasing the number of times it is
+resized as it grows. B<Worse> - in any environment that has "copy on write"
+memory for child process (such as a pre-forking server), the memory pages used
+for the shared string table rapidly need to be copied as the child process
+manipulates hashes. Hence if most of the shared string table is such that keys
+are used only in one place, there is no benefit from re-use within the perl
+interpreter, but a high cost due to more pages for the OS to copy.
+
+The perl interpreter can now be Configured to disable shared hash keys
+for "large" hashes (that are neither objects nor symbol tables).  To do
+so, add C<-Accflags='-DPERL_USE_UNSHARED_KEYS_IN_LARGE_HASHES'> to
+your F<Configure> options.  "Large" is a heuristic -- currently the
+heuristic is that sharing is disabled when adding a key to a hash
+triggers allocation of more storage, and the hash has more than 42 keys.
+
+This B<might> cause slightly increased memory usage for programs that create
+(unblessed) data structures that contain multiple large hashes that share the
+same keys. But generally our testing suggests that for the specific cases
+described it is a win, and other code is unaffected.
+
+=item *
+
+In certain scenarios, creation of new scalars is now noticeably faster.
+
+For example, the following code is now executing ~30% faster:
+
+    $str = "A" x 64;
+    for (0..1_000_000) {
+        @svs = split //, $str
+    }
+

+
+=head1 Configuration and Compilation
+
+=over 4
+
+=item *
+
+The Perl C source code now uses some C99 features, which we have verified are
+supported by all compilers we target. This means that Perl's headers now
+contain some code that is legal in C99 but not C89.
+
+This may cause problems for some XS modules that unconditionally add
+C<-Werror=declaration-after-statement> to their C compiler flags if compiling
+with gcc or clang. Earlier versions of Perl support long obsolete compilers
+that are strict in rejecting certain C99 features, particularly mixed
+declarations and code, and hence it makes sense for XS module authors to audit
+that their code does not violate this. However, doing this is now only
+possible on these earlier versions of Perl, hence these modules need to be
+changed to only add this flag for C<<$] < 5.035005>>.
+
+=item *
+
+The makedepend step is now run in parallel by using make
+
+When using MAKEFLAGS=-j8, this significantly reduces the time required for:
+
+    sh ./makedepend MAKE=make cflags
+
+=item *
+
+F<Configure> now tests whether C<< #include <xlocale.h> >> is required
+to use the POSIX 1003 thread-safe locale functions or some related
+extensions.  This prevents problems where a non-public F<xlocale.h> is
+removed in a library update, or F<xlocale.h> isn't intended for public
+use. (github L<#18936|https://github.com/Perl/perl5/pull/18936>)

+
+=over 4
+
+=item C<keys %ENV> on VMS returns consistent results
+
+On VMS entries in the C<%ENV> hash are loaded from the OS environment on
+first access, hence the first iteration of C<%ENV> requires the entire
+environment to be scanned to find all possible keys. This initialisation had
+always been done correctly for full iteration, but previously was not
+happening for C<%ENV> in scalar context, meaning that C<scalar %ENV> would
+return 0 if called before any other C<%ENV> access, or would only return the
+count of keys accessed if there had been no iteration.
+
+These bugs are now fixed - C<%ENV> and C<keys %ENV> in scalar context now
+return the correct result - the count of all keys in the environment.

+=head1 Internal Changes
+
+=over 4
+
+=item *
+
+Since the removal of PERL_OBJECT in Perl 5.8, PERL_IMPLICIT_CONTEXT and
+MULTIPLICITY have been synonymous and they were being used interchangeably.
+To simplify the code, all instances of PERL_IMPLICIT_CONTEXT have been
+replaced with MULTIPLICITY.
+
+PERL_IMPLICIT_CONTEXT will remain defined for compatibility with XS modules.
+
+=item *
+
+The API constant formerly named C<G_ARRAY>, indicating list context, has now
+been renamed to a more accurate C<G_LIST>.  A compatibilty macro C<G_ARRAY> has
+been added to allow existing code to work unaffected.  New code should be
+written using the new constant instead.  This is supported by C<Devel::PPPort>
+version 3.63.
+
+=item *
+
+Macros have been added to F<perl.h> to facilitate version comparisons:
+C<PERL_GCC_VERSION_GE>, C<PERL_GCC_VERSION_GT>, C<PERL_GCC_VERSION_LE> and
+C<PERL_GCC_VERSION_LT>.
+
+Inline functions have been added to F<embed.h> to determine the position of
+the least significant 1 bit in a word: C<lsbit_pos32> and C<lsbit_pos64>.
+
+=item *
+
+C<Perl_ptr_table_clear> has been deleted. This has been marked as deprecated
+since v5.14.0 (released in 2011), and is not used by any code on CPAN.

+phase (i.e., PL_phase value).

+
+=item *
+
+New equality-test functions C<sv_numeq> and C<sv_streq> have been added, along
+with C<..._flags>-suffixed variants.  These expose a simple and consistent API
+to perform numerical or string comparison which is aware of operator
+overloading.
+
+=item *
+
+Reading the string form of an integer value no longer sets the flag C<SVf_POK>.
+The string form is still cached internally, and still re-read directly by the
+macros C<SvPV(sv)> I<etc> (inline, without calling a C function). XS code that
+already calls the APIs to get values will not be affected by this change. XS
+code that accesses flags directly instead of using API calls to express its
+intent I<might> break, but such code likely is already buggy if passed some
+other values, such as floating point values or objects with string overloading.

+      COW_REFCNT = 1
+
+(One can't rely on the presence or absence of the flag C<SVf_IsCOW> to
+determine the history of operations on a scalar.)
+
+Previously both cases would be indistinguishable, with all 4 flags set:
+
+    SV = PVIV(0x55d4d62edaf0) at 0x55d4d62f0930
+      REFCNT = 1

+      IV = 42
+      PV = 0x55d4d62e1740 "42"\0
+      CUR = 2
+      LEN = 10
+
+(and possibly C<SVf_IsCOW>, but not always)
+
+This now means that if XS code I<really> needs to determine which form a value
+was first written as, it should implement logic roughly
+
+    if (flags & SVf_IOK|SVf_NOK) && !(flags & SVf_POK)
+        serialize as number
+    else if (flags & SVf_POK)
+        serialize as string
+    else
+        the existing guesswork ...
+
+Note that this doesn't cover "dualvars" - scalars that report different
+values when asked for their string form or number form (such as C<$!>).
+Most serialization formats cannot represent such duplicity.
+
+I<The existing guesswork> remains because as well as dualvars, values might
+be C<undef>, references, overloaded references, typeglobs and other things that
+Perl itself can represent but do not map one-to-one into external formats, so
+need some amount of approximation or encapsulation.
+
+=item *
+
+C<sv_dump> (and L<Devel::Peek>’s C<Dump> function) now escapes high-bit
+octets in the PV as hex rather than octal. Since most folks understand hex
+more readily than octal, this should make these dumps a bit more legible.

+to C<NEXTKEY>. This internal state is freed immediately when tie hash iteration

+perldelta - what is new for perl v5.36.1
 
 =head1 DESCRIPTION
 
-This document describes differences between the 5.34.0 release and the 5.36.0
+This document describes differences between the 5.36.0 release and the 5.36.1
 release.
 
-=head1 Core Enhancements
-
-=head2 C<use v5.36>
-
-As always, C<use v5.36> turns on the feature bundle for that version of Perl.
-
-The 5.36 bundle enables the C<signatures> feature.  Introduced in Perl version
-5.20.0, and modified several times since, the subroutine signatures feature is
-now no longer considered experimental. It is now considered a stable language
-feature and no longer prints a warning.
-
-    use v5.36;
-
-    sub add ($x, $y) {
-      return $x + $y;
-    }
-
-Despite this, certain elements of signatured subroutines remain experimental;
-see below.
-
-The 5.36 bundle enables the C<isa> feature.  Introduced in Perl version 5.32.0,
-this operator has remained unchanged since then. The operator is now considered
-a stable language feature.  For more detail see L<perlop/Class Instance
-Operator>.
-
-The 5.36 bundle also I<disables> the features C<indirect>, and
-C<multidimensional>.  These will forbid, respectively: the use of "indirect"
-method calls (like C<$x = new Class;>); the use of a list expression as a hash
-key to simulate sparse multidimensional arrays.  The specifics of these changes
-can be found in L<feature>, but the short version is: this is a bit like having
-more C<use strict> turned on, disabling features that cause more trouble than
-they're worth.
-
-Furthermore, C<use v5.36> will also enable warnings as if you'd written C<use
-warnings>.
-
-Finally, with this release, the experimental C<switch> feature, present in
-every feature bundle since they were introduced in v5.10, has been removed from
-the v5.36 bundle.  If you want to use it (against our advice), you'll have to
-enable it explicitly.
-
-=head2 -g command-line flag
-
-A new command-line flag, -g, is available. It is a simpler alias for -0777.
-
-For more information, see L<perlrun/-g>.
-
-=head2 Unicode 14.0 is supported
-
-See L<https://www.unicode.org/versions/Unicode14.0.0/> for details.
-
-=head2 regex sets are no longer considered experimental
-
-Prior to this release, the regex sets feature (officially named
-"Extended Bracketed Character Classes") was considered experimental.
-Introduced in Perl version 5.18.0, and modified several times since,
-this is now considered a stable language feature and its use no longer
-prints a warning.  See L<perlrecharclass/Extended Bracketed Character
-Classes>.
-
-=head2 Variable length lookbehind is mostly no longer considered experimental
-
-Prior to this release, any form of variable length lookbehind was
-considered experimental. With this release the experimental status has
-been reduced to cover only lookbehind that contains capturing parenthesis.
-This is because it is not clear if
-
-    "aaz"=~/(?=z)(?<=(a|aa))/
-
-should match and leave $1 equaling "a" or "aa". Currently it will match
-the longest possible alternative, "aa". While we are confident that the overall
-construct will now match only when it should, we are not confident that we
-will keep the current "longest match" behavior.
-
-=head2 SIGFPE no longer deferred
-
-Floating-point exceptions are now delivered immediately, in the same way
-as other "fault"-like signals such as SIGSEGV. This means one has at
-least a chance to catch such a signal with a C<$SIG{FPE}> handler, e.g.
-so that C<die> can report the line in perl that triggered it.
-
-=head2 Stable boolean tracking
-
-The "true" and "false" boolean values, often accessed by constructions like
-C<!!0> and C<!!1>, as well as being returned from many core functions and
-operators, now remember their boolean nature even through assignment into
-variables. The new function C<is_bool()> in L<builtin> can check whether
-a value has boolean nature.
-
-This is likely to be useful when interoperating with other languages or
-data-type serialisation, among other places.
-
-=head2 iterating over multiple values at a time (experimental)
-
-You can now iterate over multiple values at a time by specifying a list of
-lexicals within parentheses. For example,
-
-    for my ($key, $value) (%hash) { ... }
-    for my ($left, $right, $gripping) (@moties) { ... }
-
-Prior to perl v5.36, attempting to specify a list after C<for my> was a syntax
-error.
-
-This feature is currently experimental and will cause a warning of category
-C<experimental::for_list>.  For more detail see L<perlsyn/Compound Statements>.
-See also L</builtin::indexed> in this document, which is a handy companion to
-n-at-a-time foreach.
-
-=head2 builtin functions (experimental)
-
-A new core module L<builtin> has been added, which provides documentation for
-new always-present functions that are built into the interpreter.
-
-    say "Reference type of arrays is ", builtin::reftype([]);
-
-It also provides a lexical import mechanism for providing short name versions
-of these functions.
-
-    use builtin 'reftype';
-    say "Reference type of arrays is ", reftype([]);
-
-This builtin function mechanism and the functions it provides are all
-currently B<experimental>.  We expect that C<builtin> itself will cease to be
-experimental in the near future, but that individual functions in it may become
-stable on an ongoing basis.  Other functions will be added to C<builtin> over
-time.
-
-For details, see L<builtin>, but here's a summary of builtin functions in
-v5.36:
-
-=over 4
-
-=item builtin::trim
-
-This function treats its argument as a string, returning the result of removing
-all white space at its beginning and ending.
-
-=item builtin::indexed
-
-This function returns a list twice as big as its argument list, where each item
-is preceded by its index within that list. This is primarily useful for using
-the new C<foreach> syntax with multiple iterator variables to iterate over an
-array or list, while also tracking the index of each item:
-
-    use builtin 'indexed';
-
-    foreach my ($index, $val) (indexed @array) {
-        ...
-    }
-
-=item builtin::true, builtin::false, builtin::is_bool
-
-C<true> and C<false> return boolean true and false values.  Perl is still perl,
-and doesn't have strict typing of booleans, but these values will be known to
-have been created as booleans.  C<is_bool> will tell you whether a value was
-known to have been created as a boolean.
-
-=item builtin::weaken, builtin::unweaken, builtin::is_weak
-
-These functions will, respectively: weaken a reference; strengthen a reference;
-and return whether a reference is weak.  (A weak reference is not counted for
-garbage collection purposes.  See L<perlref>.)  These can take the place of
-some similar routines in L<Scalar::Util>.
-
-=item builtin::blessed, builtin::refaddr, builtin::reftype
-
-These functions provide more data about references (or non-references,
-actually!) and can take the place of similar routines found in L<Scalar::Util>.
-
-=item builtin::ceil, builtin::floor
-
-C<ceil> returns the smallest integer greater than or equal to its argument.
-C<floor> returns the largest integer less than or equal to its argument.  These
-can take the place of similar routines found in L<POSIX>.
-
-=back
-
-=head2 C<defer> blocks (experimental)
-
-This release adds support for C<defer> blocks, which are blocks of code
-prefixed by the C<defer> modifier. They provide a section of code which runs
-at a later time, during scope exit.
-
-In brief, when a C<defer> block is reached at runtime, its body is set aside to
-be run when the enclosing scope is exited.  It is unlike a UNITCHECK (among
-other reasons) in that if the block I<containing> the C<defer> block is exited
-before the block is reached, it will not be run.
-
-C<defer> blocks can be used to take the place of "scope guard" objects where an
-object is passed a code block to be run by its destructor.
-
-For more information, see L<perlsyn/"defer blocks">.
-
-=head2 try/catch can now have a C<finally> block (experimental)
-
-The experimental C<try>/C<catch> syntax has been extended to support an
-optional third block introduced by the C<finally> keyword.
-
-    try {
-        attempt();
-        print "Success\n";
-    }
-    catch ($e) {
-        print "Failure\n";
-    }
-    finally {
-        print "This happens regardless\n";
-    }
-
-This provides code which runs at the end of the C<try>/C<catch> construct,
-even if aborted by an exception or control-flow keyword. They are similar
-to C<defer> blocks.
-
-For more information, see L<perlsyn/"Try Catch Exception Handling">.
-
-=head2 non-ASCII delimiters for quote-like operators (experimental)
-
-Perl traditionally has allowed just four pairs of string/pattern
-delimiters: S<C<( )>> S<C<{ }>> S<C<[ ]>> and S<C<< < > >>>, all in the
-ASCII range.  Unicode has hundreds more possibilities, and using this
-feature enables many of them.  When enabled, you can say S<C<qr« »>> for
-example, or S<C<use utf8; q𝄃string𝄂>>.  See L<feature/The
-'extra_paired_delimiters' feature> for details.
-
-=head2 @_ is now experimental within signatured subs
-
-Even though subroutine signatures are now stable, use of the legacy arguments
-array (C<@_>) with a subroutine that has a signature I<remains> experimental,
-with its own warning category.  Silencing the C<experimental::signatures>
-warning category is not sufficient to dismiss this.  The new warning is emitted
-with the category name C<experimental::args_array_with_signatures>.
-
-Any subroutine that has a signature and tries to make use of the defaults
-argument array or an element thereof (C<@_> or C<$_[INDEX]>), either
-explicitly or implicitly (such as C<shift> or C<pop> with no argument) will
-provoke a warning at compile-time:
-
-    use v5.36;
-
-    sub f ($x, $y = 123) {
-      say "The first argument is $_[0]";
-    }
-
-Z<>
-
-    Use of @_ in array element with signatured subroutine is experimental
-    at file.pl line 4.
-
-The behaviour of code which attempts to do this is no longer specified, and
-may be subject to change in a future version.

+L<perl5360delta>, which describes differences between 5.35.0 and 5.36.0.
 
 =head1 Incompatible Changes
 
-=head2 A physically empty sort is now a compile-time error
-
-    @a = sort @empty; # unaffected
-    @a = sort;        # now a compile-time error
-    @a = sort ();     # also a compile-time error
-
-A bare sort used to be a weird way to create an empty list; now it croaks
-at compile time. This change is intended to free up some of the syntax space
-for possible future enhancements to C<sort>.
-
-=head1 Deprecations
-
-=head2 C<use VERSION> (where VERSION is below v5.11) after C<use v5.11> is deprecated
-
-When in the scope of C<use v5.11> or later, a C<use vX> line where I<X> is
-lower than v5.11 will now issue a warning:
-
-    Downgrading a use VERSION declaration to below v5.11 is deprecated
-
-For example:
-
-    use v5.14;
-    say "The say statement is permitted";
-    use v5.8;                               # This will print a warning
-    print "We must use print\n";
-
-This is because the Perl team plans to change the behavior in this case.  Since
-Perl v5.12 (and parts of v5.11), strict is enabled I<unless it had previously
-been disabled>.  In other words:
-
-    no strict;
-    use v5.12;  # will not enable strict, because "no strict" preceded it
-    $x = 1;     # permitted, despite no "my" declaration
-
-In the future, this behavior will be eliminated and C<use VERSION> will
-I<always> enable strict for versions v5.12 and later.
-
-Code which wishes to mix versions in this manner should use lexical scoping
-with block syntax to ensure that the differently versioned regions remain
-lexically isolated.
-
-    {
-        use v5.14;
-        say "The say statement is permitted";
-    }
-
-    {
-        use v5.8;                           # No warning is emitted
-        print "We must use print\n";
-    }
-
-Of course, this is probably not something you ever need to do!  If the first
-block compiles, it means you're using perl v5.14.0 or later.
-
-=head1 Performance Enhancements
-
-=over 4
-
-=item *
-
-We now probe for compiler support for C11 thread local storage, and where
-available use this for "implicit context" for XS extensions making API calls for
-a threaded Perl build.  This requires fewer function calls at the C level than
-POSIX thread specific storage. We continue to use the the pthreads approach if
-the C11 approach is not available.
-
-F<Configure> run with the defaults will build an unthreaded Perl (which is
-slightly faster), but most operating systems ship a threaded Perl.
-
-=item *
-
-Perl can now be configured to no longer allocate keys for large hashes
-from the shared string table.
-
-The same internal datatype (C<PVHV>) is used for all of
-
-=over 4
-
-=item *
-
-Symbol tables
-
-=item *
-
-Objects (by default)
-
-=item *
-
-Associative arrays
-
-=back
-
-The shared string table was originally added to improve performance for blessed
-hashes used as objects, because every object instance has the same keys, so it
-is an optimisation to share memory between them. It also makes sense for symbol
-tables, where derived classes will have the same keys (typically method names),
-and the OP trees built for method calls can also share memory. The shared
-string table behaves roughly like a cache for hash keys.
-
-But for hashes actually used as associative arrays - mapping keys to values -
-typically the keys are not re-used in other hashes. For example, "seen" hashes
-are keyed by object IDs (or addresses), and logically these keys won't repeat
-in other hashes.
-
-Storing these "used just once" keys in the shared string table increases CPU
-and RAM use for no gain. For such keys the shared string table behaves as a
-cache with a 0% hit rate. Storing all the keys there increases the total size
-of the shared string table, as well as increasing the number of times it is
-resized as it grows. B<Worse> - in any environment that has "copy on write"
-memory for child process (such as a pre-forking server), the memory pages used
-for the shared string table rapidly need to be copied as the child process
-manipulates hashes. Hence if most of the shared string table is such that keys
-are used only in one place, there is no benefit from re-use within the perl
-interpreter, but a high cost due to more pages for the OS to copy.
-
-The perl interpreter can now be Configured to disable shared hash keys
-for "large" hashes (that are neither objects nor symbol tables).  To do
-so, add C<-Accflags='-DPERL_USE_UNSHARED_KEYS_IN_LARGE_HASHES'> to
-your F<Configure> options.  "Large" is a heuristic -- currently the
-heuristic is that sharing is disabled when adding a key to a hash
-triggers allocation of more storage, and the hash has more than 42 keys.
-
-This B<might> cause slightly increased memory usage for programs that create
-(unblessed) data structures that contain multiple large hashes that share the
-same keys. But generally our testing suggests that for the specific cases
-described it is a win, and other code is unaffected.
-
-=item *
-
-In certain scenarios, creation of new scalars is now noticeably faster.
-
-For example, the following code is now executing ~30% faster:
-
-    $str = "A" x 64;
-    for (0..1_000_000) {
-        @svs = split //, $str
-    }
-
-(You can read more about this one in L<[perl
-#19414]|https://github.com/Perl/perl5/pull/19414>.)
