So, talk to the devloper. The developer of the class is more god-like because it is his development. If something goes wrong with the class he has to find out what and that is easier if he can assure that clients didn't mess with certain implementation details. Sure the developer can make a mistake here, just as he can mistakes anywhere in his code. If that happens, you should report a bug. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
