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
([]).
