"Avoid inheritance" would be almost as justified :-) Problems that may arise with this case of multiple inheritance: - If you need initializers, ensure that they are all invoked - What would you do about name clashes? To avoid them your plugins need to know about each other. - State (instance attributes) is shared among all your plugins. Since you call all base classes Commands, Python's double-underscore hack won't work. Peter -- http://mail.python.org/mailman/listinfo/python-list
