helping out people who want to experiment with prototype OO. The request is make it possible to write:

def Account.deposit(self, v): self.balance += v

Could function decorators be used for this? Something like:

@attach_to_object(Account) def deposit (self, v): ... del deposit

The decorator couldn't delete the binding of 'deposit' in the current namespace, however. Decorators could return a magic value that meant "don't create a binding for the function", but that seems only useful for this one use case. Or maybe the decorator would record the name internally, and after defining all the methods you'd call a cleanup function that deleted them from the module namespace.
