Oh I agree entirely. They are just equivalent ways of managing the complexity of large projects.
I guess interfaces are "providing" specifications, and generics are "receiving" specifications, so single dispatch methods can be identical to interfaces only "inverted". Therefore, as there is no interface equivalent of full multi-methods, it shows that multimethods are the only primative you need to implement all of the above Cheers, Ben -- http://mail.python.org/mailman/listinfo/python-list
