31 =head1 Core Enhancements
33 XXX New core language features go here. Summarise user-visible core language
34 enhancements. Particularly prominent performance optimisations could go
35 here, but most should go in the L</Performance Enhancements> section.
37 [ List each enhancement as a =head2 entry ]
39 =head2 Single term prototype
41 The C<+> prototype is a special alternative to C<$> that will act like
42 C<\[@%]> when given a literal array or hash variable, but will otherwise
43 force scalar context on the argument. This is useful for functions which
44 should accept either a literal array or an array reference as the argument:
48 die "Not an array or arrayref" unless ref $aref eq 'ARRAY';
52 When using the C<+> prototype, your function must check that the argument
53 is of an acceptable type.
55 =head2 C<use re '/flags';>
57 The C<re> pragma now has the ability to turn on regular expression flags
58 till the end of the lexical scope:
61 "foo" =~ / (.+) /; # /x implied
63 See L<re/'/flags' mode> for details.
65 =head2 Statement labels can appear in more places
67 Statement labels can now occur before any type of statement or declaration,
70 =head2 C<use feature "unicode_strings"> now applies to more regex matching
72 Another chunk of the L<perlunicode/The "Unicode Bug"> is fixed in this
73 release. Now, regular expressions compiled within the scope of the
74 "unicode_strings" feature (or under the "u" regex modifier (specifiable
75 currently only with infix notation C<(?u:...)> or via C<use re '/u'>)
76 will match the same whether or not the target string is encoded in utf8,
77 with regard to C<[[:posix:]]> character classes
79 Work is underway to add the case sensitive matching to the control of
80 this feature, but was not complete in time for this dot release.
82 =head2 Array and hash container functions accept references
84 All built-in functions that operate directly on array or hash
85 containers now also accept hard references to arrays or hashes:
87 |----------------------------+---------------------------|
88 | Traditional syntax | Terse syntax |
89 |----------------------------+---------------------------|
90 | push @$arrayref, @stuff | push $arrayref, @stuff |
91 | unshift @$arrayref, @stuff | unshift $arrayref, @stuff |
92 | pop @$arrayref | pop $arrayref |
93 | shift @$arrayref | shift $arrayref |
94 | splice @$arrayref, 0, 2 | splice $arrayref, 0, 2 |
95 | keys %$hashref | keys $hashref |
96 | keys @$arrayref | keys $arrayref |
97 | values %$hashref | values $hashref |
98 | values @$arrayref | values $arrayref |
99 | ($k,$v) = each %$hashref | ($k,$v) = each $hashref |
100 | ($k,$v) = each @$arrayref | ($k,$v) = each $arrayref |
101 |----------------------------+---------------------------|
103 This allows these built-in functions to act on long dereferencing chains
104 or on the return value of subroutines without needing to wrap them in
107 push @{$obj->tags}, $new_tag; # old way
108 push $obj->tags, $new_tag; # new way
110 for ( keys %{$hoh->{genres}{artists}} ) {...} # old way
111 for ( keys $hoh->{genres}{artists} ) {...} # new way
113 For C<push>, C<unshift> and C<splice>, the reference will auto-vivify
114 if it is not defined, just as if it were wrapped with C<@{}>.
116 Calling C<keys> or C<values> directly on a reference gives a substantial
117 performance improvement over explicit dereferencing.
119 For C<keys>, C<values>, C<each>, when overloaded dereferencing is
120 present, the overloaded dereference is used instead of dereferencing the
121 underlying reftype. Warnings are issued about assumptions made in the
122 following three ambiguous cases:
124 (a) If both %{} and @{} overloading exists, %{} is used
125 (b) If %{} overloading exists on a blessed arrayref, %{} is used
126 (c) If @{} overloading exists on a blessed hashref, @{} is used
130 The C</r> flag, which was added to C<s///> in 5.13.2, has been extended to
131 the C<y///> operator.
133 It causes it to perform the substitution on a I<copy> of its operand,
134 returning that copy instead of a character count.

148 There are no changes intentionally incompatible with 5.XXX.XXX. If any
149 exist, they are bugs and reports are welcome.
151 [ List each incompatible change as a =head2 entry ]
153 =head2 Dereferencing typeglobs
155 If you assign a typeglob to a scalar variable:
159 the glob that is copied to C<$glob> is marked with a special flag
160 indicating that the glob is just a copy. This allows subsequent assignments
161 to C<$glob> to overwrite the glob. The original glob, however, is
164 Many Perl operators did not distinguish between these two types of globs.
165 This would result in strange behaviour in edge cases: C<untie $scalar>
166 would do nothing if the last thing assigned to the scalar was a glob
167 (because it treated it as C<untie *$scalar>, which unties a handle).
168 Assignment to a glob slot (e.g., C<(*$glob) = \@some_array>) would simply
169 assign C<\@some_array> to C<$glob>.
171 To fix this, the C<*{}> operator (including the C<*foo> and C<*$foo> forms)
172 has been modified to make a new immutable glob if its operand is a glob
173 copy. Various operators that make a distinction between globs and scalars
174 have been modified to treat only immutable globs as globs.
176 This causes an incompatible change in code that assigns a glob to the
177 return value of C<*{}> when that operator was passed a glob copy. Take the
178 following code, for instance:
183 The C<*$glob> on the second line returns a new immutable glob. That new
184 glob is made an alias to C<*bar>. Then it is discarded. So the second
185 assignment has no effect.
187 The upside to this incompatible change is that bugs

679 A new, experimental API has been added for accessing the internal
680 structure that Perl uses for C<%^H>. See the functions beginning with
681 C<cophh_> in L<perlapi>.
685 A stash can now have a list of effective names in addition to its usual
686 name. The first effective name can be accessed via the C<HvENAME> macro,

691 C<hv_ename_delete>. These two functions are I<not> part of the API.

717 has been added to replace assignment to C<CvSTASH()>. This is to ensure
718 that backreferences are handled properly. These macros are not part of the

741 fixed to work with statements ending with C<}>
742 L<[perl #78222]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=78222>.
746 The C<parse_fullstmt> C function added in 5.13.5 has been fixed to work
747 when called while an expression is being parsed.
751 Characters in the Latin-1 non-ASCII range (0x80 to 0xFF) used not to match
752 themselves if the string happened to be UTF8-encoded internally, the
753 regular expression was not, and the character in the regular expression was
754 inside a repeated group (e.g.,
755 C<Encode::decode_utf8("\303\200") =~ /(\xc0)+/>)
756 L<[perl #78464]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=78464>.

767 L<[perl #78488]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=78488>.
771 Various bugs related to typeglob dereferencing have been fixed. See
772 L</Dereferencing typeglobs>, above.
776 The C<SvPVbyte> function available to XS modules now calls magic before
777 downgrading the SV, to avoid warnings about wide characters
778 L<[perl #72398]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=72398>.
782 The C<=> operator used to ignore magic (e.g., tie methods) on its
783 right-hand side if the scalar happened to hold a typeglob. This could
784 happen if a typeglob was the last thing returned from or assigned to a tied
786 L<[perl #77498]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=77498>.
790 C<sprintf> was ignoring locales when called with constant arguments
791 L<[perl #78632]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=78632>.
795 A non-ASCII character in the Latin-1 range could match both a Posix
796 class, such as C<[[:alnum:]]>, and its inverse C<[[:^alnum:]]>. This is
797 now fixed for regular expressions compiled under the C<"u"> modifier.
798 See L</C<use feature "unicode_strings"> now applies to more regex matching>.

805 L<[perl #78674]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=78674>.
809 Typeglob assignments would crash if the glob's stash no longer existed, if
810 the glob assigned to was named 'ISA' or the glob on either side of the
811 assignment contained a subroutine.
815 Calling C<< ->import >> on a class lacking an import method could corrupt the stack result in strange behaviour. For instance,
817 push @a, "foo", $b = bar->import;
819 would assign 'foo' to C<$b>
820 L<[perl #63790]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=63790>.

826 L<[perl #77358]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=77358>.
830 C<.=> followed by C<< <> >> or C<readline> would leak memory if C<$/>
831 contained characters beyond the octet range and the scalar assigned to
832 happened to be encoded as UTF8 internally
833 L<[perl #72246]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=72246>.
837 The C<recv> function could crash when called with the MSG_TRUNC flag
838 L<[perl #75082]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=75082>.
842 Evaluating a simple glob (like C<*a>) was calling get-magic on the glob,
843 even when its contents were not being used
844 L<[perl #78580]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=78580>.
846 This bug was introduced in 5.13.2 and did not affect earlier perl versions.
850 Matching a Unicode character against an alternation containing characters
851 that happened to match continuation bytes in the former's UTF8
852 representation (C<qq{\x{30ab}} =~ /\xab|\xa9/>) would cause erroneous
854 L<[perl #70998]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=70998>.
858 C<s///r> (added in 5.13.2) no longer leaks.
862 =head1 Known Problems
864 XXX Descriptions of platform agnostic bugs we know we can't fix go here. Any
865 tests that had to be C<TODO>ed for the release would be noted here, unless
866 they were specific to a particular platform (see below).
868 This is a list of some significant unfixed bugs, which are regressions
869 from either 5.XXX.XXX or 5.XXX.XXX.
871 [ List each fix as a =item entry ]
883 XXX If any significant core contributor has died, we've added a short obituary
886 Randy Kobes, creator of the kobesearch alternative to search.cpan.org and
887 contributor/maintainer to several core Perl toolchain modules, passed away
888 on September 18, 2010 after a battle with lung cancer. His contributions
889 to the Perl community will be missed.

895 =head1 Reporting Bugs
897 If you find what you think is a bug, you might check the articles
898 recently posted to the comp.lang.perl.misc newsgroup and the perl
899 bug database at http://rt.perl.org/perlbug/ . There may also be
900 information at http://www.perl.org/ , the Perl Home Page.
902 If you believe you have an unreported bug, please run the B<perlbug>
903 program included with your release. Be sure to trim your bug down
904 to a tiny but sufficient test case. Your bug report, along with the
905 output of C<perl -V>, will be sent off to perlbug@perl.org to be
906 analysed by the Perl porting team.
908 If the bug you are reporting has security implications, which make it
909 inappropriate to send to a publicly archived mailing list, then please send
910 it to perl5-security-report@perl.org. This points to a closed subscription
911 unarchived mailing list, which includes all the core committers, who be able
912 to help assess the impact of issues, figure out a resolution, and help
913 co-ordinate the release of patches to mitigate or fix the problem across all
914 platforms on which Perl is supported. Please only use this address for
915 security issues in the Perl core, not for modules independently
