I'm not sure where you got the idea that he was doing type checking, unless you just saw the word "TypeError" and made a knee-jerk assumption about what was he was doing. If you'd have bothered trying to understand the post you would have seen that he was filtering arguments by name. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
