I agree that is one way to solve it. However, if "hiding" the function can be avoided alltogether, then it's even better. On a sidenote, i am not sure Python's decorator design was such a great idea. Maybe it should have been restricted to setting attributes (like C# and also java IIRC) and then a way to get those attributed functions on a per-class, per-module or even global basis. best, holger _______________________________________________ py-dev mailing list py-dev@codespeak.net http://codespeak.net/mailman/listinfo/py-dev
