note dragonchild Roles don't -have- attributes. Roles can -provide- attributes to the classes they are composed into. If you have a Cat and Dog, each of which does Pet, then if you have a $cat instance and a $dog instance, the $.collar attribute of each is separate. They aren't shared in any sense. Therefore, Perl6 roles -are- stateless in that the role itself doesn't have any state. (Which makes sense given that you cannot instantiate a role.) <!-- Node text goes above.
