Suggested Patches

   Steve Hay provided a patch in [79]Perl #123113 to add optional GCC-only
   support for using long doubles on Win32.

   Steve also provided a patch in [80]Perl #125827 to [81]PathTools to not
   require() modules in subs likely to be in loops.

   Hauke D. provided a patch in [82]Perl #132475 to handle LAYER argument in
   Tie::StdHandle::BINMODE.

Discussion

   Paul Evans and Zefram [83]discuss (Signature parsing compiler functions)
   an API for parsing signatures.

   Zefram has a [84]suggestion of utilizing the smart match syntax to
support
   type checks in signatures.

   Zefram also [85]suggested moving signatures syntax to square brackets
   ([]).
