-[ Any text flagged as XXX needs to be processed before release. ]
-
perldelta - what is new for perl v5.11.2
=head1 DESCRIPTION
This document describes differences between the 5.11.1 release and
the 5.11.2 release.
-=head1 Notice
-
-XXX Unlikely to need this section.
-
-=head1 Incompatible Changes
-
-=head2 Use of C<:=> to mean an empty attribute list is now deprecated.
-
-An accident of Perl's parser meant that these constructions were all equivalent:
-
- my $pi := 4;
- my $pi : = 4;
- my $pi : = 4;
-
-with the C<:> being treated as the start of an attribute list, which ends
-before the C<=>. As whitespace is not significant here, all are parsed as an
-empty attribute list, hence all the above are equivalent to, and better written
-as
-
- my $pi = 4;
-
-because no attribute processing is done for an empty list.
-
-As is, this meant that C<:=> cannot be used as a new token, without silently
-changing the meaning of existing code. Hence that particular form is now
-deprecated, and will become a syntax error. If it is absolutely necessary to
-have empty attribute lists (for example, because of a code generator) then
-avoid the warning by adding a space before the C<=>.
-
=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 qr overloading
It is now possible to overload the C<qr//> operator, that is, conversion
This module is mainly used for test purposes, and is not normally
installed, but also serves as an example of how to use the new mechanism.
+=head2 Lexer API
+
+We have added a public API for the lowest layers of lexing. This is meant
+to provide a solid foundation for the parsing that Devel::Declare and
+similar modules do, and it complements the pluggable keyword mechanism.
+The API consists of some existing variables combined with some new functions,
+all marked as experimental (which making them public certainly is).
+
=head2 APIs for more internals
The lowest layers of the lexer and parts of the pad system now have C
mechanism, so extensions could only properly influence subroutine names
that appeared with an C<&> sigil.)
-=head1 New Platforms
-
-XXX List any platforms that this version of perl compiles on, that previous
-versions did not. These will either be enabled by new files in the F<hints/>
-directories, or new subdirectories and F<README> files at the top level of the
-source tree.
-
=head1 Modules and Pragmata
-XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
-go here, in a list ordered by distribution name. Minimally it should be the
-module version, but it's more useful to the end user to give a paragraph's
-summary of the module's changes. In an ideal world, dual-life modules would
-have a F<Changes> file that could be cribbed.

as the main perldelta
