Good point, the duck typing mismatches on "x in y" and there's nothing that can be done about that. Imagine a Bag (multiset) object; it can have multiple occurrences of a single value. A keys() operation on it should return unique items, but values() should return the multiple occurrences. -- http://mail.python.org/mailman/listinfo/python-list
