The Perl 5 Porters are currently working on Perl 5.15, the development track that will end up as Perl 5.16. By reading the perldelta515* documentation, you can get a peek at what will mostly likely be in the next maintenance version of Perl. You need to read each of the perldelta5* in a development series because they only document the changes in to the previous development release, not the cumulative changes since the last major release.
We’ll cover these features, although we might have to stretch some of the posts a bit since some of these aren’t that radical:
- Perl v5.16 now sets proper magic on lexical $_
__SUB__returns a reference to the current subroutine- Proper case folding with
fcand\F - Look up Unicode properties with an inversion map
CORE::works on all keywordscontinueno longer requires the “switch” feature- $$ is no longer read-only
\N{...}can now have Unicode loose name matching- Features inside the debugger
- Breakpoints with file names
