16 =head1 Core Enhancements
18 =head2 builtin Functions
20 A new core module L<builtin> has been added, which provides documentation for
21 new always-present functions that are built into the interpreter.
23 say "Reference type of arrays is ", builtin::reftype([]);
25 It also provides a lexical import mechanism for providing short name versions
28 use builtin 'reftype';
29 say "Reference type of arrays is ", reftype([]);
31 An initial set of functions exists to provide convenient access to stable
32 boolean values, weakening references, and inspecting properties of references.
34 This builtin function mechanism and the functions it provides are all
35 currently B<experimental>.
37 For more information, see the L<builtin> module.

115 =head1 Platform Support
118 =head2 Platform-Specific Notes
124 This update enables us to build EBCDIC static/dynamic
125 and 31-bit/64-bit addressing mode Perl. The number of
126 tests that pass is consistent with the baseline before
129 These changes also provide the base support to be able to provide
130 ASCII static/dynamic and 31-bit/64-bit addressing mode Perl.
135 =head1 Internal Changes
139 =item * A new phase_name() interface provides access to the name
140 for each interpreter phase (i.e., PL_phase value).
142 =item * The changes in v5.35.5 for how memory for hash iterator state was allocated could cause unbounded memory consumption (until process exit). The bug that caused this has been fixed - memory consumption is now stable, and potentially lower than v5.35.4 and earlier.
144 =for The v5.36.0 perldelta, just drop the paragraph about the bugfix.
149 =head1 Selected Bug Fixes
155 When bareword filehandles are disabled, the parser was interpreting
156 any bareword as a filehandle, even when immediatey followed by parens.

181 The list above is almost certainly incomplete as it is automatically
182 generated from version control history. In particular, it does not include
183 the names of the (very much appreciated) contributors who reported issues to
184 the Perl bug tracker.
186 Many of the changes included in this version originated in the CPAN modules
187 included in Perl's core. We're grateful to the entire CPAN community for
188 helping Perl to flourish.
