Are you wanting this to go through all of the Class/Role's methods and check that the $object.can() them? I think that perhaps .can($Method) (where $Method.isa(Meta::Method)) would be acceptable, then .can(Role) can either be defined to be .can(all(Role.get_methods)), or we just leave the user to use that snippet - after all, such extreme duck typing is expensive and shouldn't be huffmanised overly IMHO. We want people to use the Role objects unless they have a really good reason, and besides you can always just wrap things up in a Facade if you have to. Sam.Thread Previous | Thread Next
