With the builtin 'dict' implementation, dict.__contains__() use the dict_has_key() C function, and does not touch your subclass __getitem__ python method. I don't think it can be called 'safe'... it may lead to very inconsistent behavior. It's like overridind both __eq__ and __ge__ with a different behavior. It's better for you to override __contains__() too. -- Pedro Werneck -- http://mail.python.org/mailman/listinfo/python-list
