You've probably already heard of Sartak's awesome\nMooseX::Role::Parameterized.

\n

As of version 0.25, MooseX::Declare provides some nice sugar for\nthat. This is what it looks like:

\n
use MooseX::Declare;\n\nrole Counter (Str :$name) {\n  has $name => (is => 'rw', isa => 'Int', default => 0);\n\n  method "increment_${name}" {\n    $self->$name( $self->$name + 1 );\n  }\n\n  method "reset_${name}" {\n    $self->$name(0);\n  }\n}\n\nclass MyGame::Weapon {\n  with Counter => { name => 'enchantment' };\n}\n\nclass MyGame::Wand {\n  with Counter => { name => 'zapped' };\n}\n
\n

Just thought I'd let you know, since i haven't gotten around to\nactually document this. In case you like it, have some spare\ntuits, and want to help out, the repository is\nright here :-)
