This brings up an issue another poster brought up: In my usage of the term "parent", I use it to mean the class that is a product of object composition: class Parent(child1, child2): pass I figure that it is this "Parent" class which must manage the methods that it is inheriting with child1 and child2 -- mixins or otherwise. In this usage, super() should be called "delegate" as whatever I don't accomplish in my specialized Parent class, I will get the child classes to do. Python automagically delegates any methods that I don't define in Parent to methods found in child1 and child2. It seems the issues that everyone encounters with multiple inheritance, mixins, and such has more to do with terminology (and proper implementation) than in actuality. zipher
