-perldelta - what is new for perl v5.13.5
+perl5135delta - what is new for perl v5.13.5
=head1 DESCRIPTION
L<perl5134delta>, which describes differences between 5.13.3 and
5.13.4.
-=head1 Notice

-XXX Any important notices here

=head1 Core Enhancements
-XXX New core language features go here. Summarise user-visible core language
-enhancements. Particularly prominent performance optimisations could go
-here, but most should go in the L</Performance Enhancements> section.
-
=head2 Adjacent pairs of nextstate opcodes are now optimized away
Previously, in code such as
the C<nextstate> op would remain, resulting in a runtime op dispatch of
C<nextstate>, C<nextstate>, ...
-The execution of a sequence of C<nexstate> ops is indistinguishable from just
-the last C<nextstate> op, so teach the peephole optimiser to eliminate the first
-of a pair of C<nextstate> ops. (Except where the first carries a label, as
-labels mustn't be eliminated by the optimiser, and label usage isn't
-conclusively known at compile time.)
+The execution of a sequence of C<nextstate> ops is indistinguishable from just

+a pair of C<nextstate> ops, except where the first carries a label, since labels
+must not be eliminated by the optimizer and label usage isn't conclusively known

-=head1 Security
+=head2 API function to parse statements
-XXX Any security-related notices go here. In particular, any security
-vulnerabilities closed should be noted here rather than in the
-L</Selected Bug Fixes> section.
+The C<parse_fullstmt> function has been added to allow parsing of a single
+complete Perl statement. See L<perlapi> for details.
-[ List each security issue as a =head2 entry ]
+=head2 API functions for accessing the runtime hinthash
+
+A new C API for introspecting the hinthash C<%^H> at runtime has been added.
+See C<cop_hints_2hv>, C<cop_hints_fetchpvn>, C<cop_hints_fetchpvs>,
+C<cop_hints_fetchsv>, and C<hv_copy_hints_hv> in L<perlapi> for details.
+
+=head2 C interface to C<caller()>
+
+The C<caller_cx> function has been added as an XSUB-writer's equivalent of
+C<caller()>. See L<perlapi> for details.
=head1 Incompatible Changes
+=head2 Magic variables outside the main package
+
+In previous versions of Perl, magic variables like C<$!>, C<%SIG>, etc. would
+'leak' into other packages. So C<%foo::SIG> could be used to access signals,
+C<${"foo::!"}> (with strict mode off) to access C's C<errno>, etc.
+
+This was a bug, or an 'unintentional' feature, which caused various ill effects,
+such as signal handlers being wiped when modules were loaded, etc.
+
+This has been fixed (or the feature has been removed, depending on how you see
+it).
+
+=head2 Smart-matching against array slices
+
+Previously, the following code resulted in a successful match:
+
+ my @a = qw(a y0 z);
+ my @b = qw(a x0 z);
+ $a[0 .. $#b] ~~ @b;
+
+This odd behaviour has now been fixed
+L<[perl #77468]|http://rt.perl.org/rt3//Public/Bug/Display.html?id=77468>.
+
=head2 C API changes
The first argument of the C API function C<Perl_fetch_cop_label> has changed
implementation details.
This API function was marked as "may change", and likely isn't in use outside
-the core. (Neither an unpacked CPAN, nor Google's codesearch, finds any other
+the core. (Neither an unpacked CPAN, nor Google's codesearch, finds any other
references to it.)
=head1 Deprecations
-XXX Any deprecated features, syntax, modules etc. should be listed here.
-In particular, deprecated modules should be listed here even if they are
-listed as an updated module in the L</Modules and Pragmata> section.
+=head2 Use of qw(...) as parentheses
-[ List each deprecation as a =head2 entry ]
+Historically the parser fooled itself into thinking that C<qw(...)> literals
+were always enclosed in parentheses, and as a result you could sometimes omit
+parentheses around them:
-=head1 Performance Enhancements
+ for $x qw(a b c) { ... }
-XXX Changes which enhance performance without changing behaviour go here. There
-may well be none in a stable release.
+The parser no longer lies to itself in this way. Wrap the list literal in
+parentheses, like:
-[ List each enhancement as a =item entry ]
+ for $x (qw(a b c)) { ... }
+

body they actually use, saving some space.

-=head1 Modules and Pragmata
+Compiling regular expressions has been made faster for the case where upgrading
+the regex to utf8 is necessary but that isn't known when the compilation begins.
-XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
-go here. If Module::CoreList is updated, generate an initial draft of the
-following sections using F<Porting/corelist-perldelta.pl>, which prints stub
