           package Lizard;   use Moose;
           package Spock;    use Moose;

           package Game;

           multi method play (Paper    $x, Spock    $y) { 1 }
           multi method play (Scissors $x, Paper    $y) { 1 }
           multi method play (Scissors $x, Lizard   $y) { 1 }
           multi method play (Rock     $x, Scissors $y) { 1 }
           multi method play (Rock     $x, Lizard   $y) { 1 }
           multi method play (Lizard   $x, Paper    $y) { 1 }
           multi method play (Lizard   $x, Spock    $y) { 1 }
           multi method play (Spock    $x, Rock     $y) { 1 }
           multi method play (Spock    $x, Scissors $y) { 1 }
           multi method play (Any      $x, Any      $y) { 0 }

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

DESCRIPTION

       This module provides multi method dispatch based on Moose type constraints. It does so by
       providing a "multi" keyword that extends the "method" keyword provided by
       MooseX::Method::Signatures.

       When invoking a method declared as "multi" a matching variant is being searched in all the
       declared multi variants based on the passed parameters and the declared type constraints.
       If a variant has been found, it will be invoked.  If no variant could be found, an
       exception will be thrown.
