Perl6::Signature 0.03

Perl6::Signature is a Perl module that models routine signatures as specified in Synopsis 6 of the Perl 6 documentation. These signatures offer a rich language for expressing type constraints, default values, and the optionality (among other things) of routine parameters.<br /><br />Included is a parser for the Signature language, accessors and convenience methods for querying Signature objects, and a pretty-printer for producing their canonical textual representation.<br /><br />SYNOPSIS<br /><br /> use Perl6::Signature;<br /><br /> my $sig = Perl6::Signature- >parse(<br /> ':($self: $x, Int $y = 42 where { $_ % 2 == 0 }, :$z is copy)');<br /><br /> print $sig- >s_requiredPositionalCount; # 1<br /> print $sig- >s_positionalList- >[0]- >p_label # "x"<br /> print $sig- >s_namedList- >[0]- >p_hasAccess; # "copy"<br /><br /> print $sig- >to_string;<br /> # ":($self: $x, Int $y = 42 where { $_ % 2 == 0 }, :$z is copy)"
