Why it should be a dict. With it you can only maintain the order x1<x2<x3... But by definition the order only requires x1<=x2<=x3... There are many use cases where keys are not unique. I'd prefer a list implementation, which would maintain the user defined order (cmp, key). So you could map your objects with any order. TV -- http://mail.python.org/mailman/listinfo/python-list
