Possibly. Clearly that's what one would do in any other language. What I was thinking was that if hashes are going to have a canonicalizer function *anyway*, maybe the default implementation could be overridable with a trait (or role?). But I can't actually claim to have followed perl6 development enough to be able to argue that it really makes sense. Alex
