35           my $game = Game->new;
36           $game->play(Paper->new, Rock->new);     # 1, Paper covers Rock
37           $game->play(Spock->new, Paper->new);    # 0, Paper disproves Spock

DESCRIPTION

41       This module provides multi method dispatch based on Moose type
42       constraints. It does so by providing a "multi" keyword that extends the
43       "method" keyword provided by MooseX::Method::Signatures.
44
45       When invoking a method declared as "multi" a matching variant is being
46       searched in all the declared multi variants based on the passed
47       parameters and the declared type constraints. If a variant has been
48       found, it will be invoked.  If no variant could be found, an exception
49       will be thrown.
