Mamma mia! My head just exploded. I've seen the light. So you only need to ·want· to have a protocol? That's amazing... Far beyond the claim that Python is easy. You define protocols in writing basically! Even my grandma could have her own Python protocol.
Okay, so I think I know where's the catch now -- you must rely on the fact that the protocol is implemented, there's no way to enforce it if you're expecting a parrot-like object. You'd try to call the speak() method and deal with the error if there's no such method? Thanks a lot! Guillermo -- http://mail.python.org/mailman/listinfo/python-list
