Thanks, Phillip. That's essentially what I'm talking about with CL mixins, as well (though instead of typeclass instances you usually have mixin implementations which are "mixed" into the class which wishes to provide the interface, to give it the methods). That's what I think Py3K should be using, too, instead of "duck typing", which for some reason has come to be thought of (wrongly) as a "feature".
