Perl6-Subs

This module implements much of the Perl 6 subroutine definition syntax
for Perl 5 code.  It's a source filter, so it can be broken easily.

Run 'perldoc lib/Perl6/Subs.pm' to read all about it.


SAMPLE CODE

   use Perl6::Subs;

   {
     package SomeClass;
     method something             { $self->other }
     method other       ( $me: )  { $me->yet_another( joe => 1 ) }
     method yet_another ( +$joe ) { $joe ? $self->foo : $self->bar }
   }

   sub foo ( str $a, Int $b, SomeClass ?$c ) {
      print $a, ":", $b + ($c ? $c->something : 0);
   }


WARNINGS YOU SHOULD NOT IGNORE

  * Do not use parameter names that turn into Perl quoting operators
    when their sigils are stripped: "$y", "$m", "@tr", "@q", etc.

  * Avoid putting comments into subroutine declarations.

  * Perl 6 prototypes do not imply Perl 5 prototypes.
