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.
