Generally excellent references, but "X < Y < Z < W has expected meaning, unlike C" is not much help to people who have not been exposed to similar notation (e.g. 0 <= angle < 2 * pi) in other disciplines and/or know C merely as a member of the same set as X, Y, Z and W. -- http://mail.python.org/mailman/listinfo/python-list
