Store the class object. Unfortunately, I can't store builtin methods or functions, so this breaks on most modules. Don't try to reference the __builtins__, by the way, otherwise it won't be removed and modjelly will break. > I tried for a bit to restrict things, then gave up and did it > externally.

I don't have enough control on the server to effectively restrict it externally (no running as an unprivelleged user!), so I have to lock it down as tightly as possible internally. -- http://mail.python.org/mailman/listinfo/python-list
