I can see some use for inheritance there. But keep in mind that there is no multiple inheritance at the C level, so thinking terms of "mixins" doesn't really apply. There would need to be a single base class, or just a bunch of C functions for implementations to plug into the relevant slots. -- Greg Ewing, Computer Science Dept, +--------------------------------------+ University of Canterbury, | Carpe post meridiam! | Christchurch, New Zealand | (I'm not a morning person.) | [EMAIL PROTECTED] +--------------------------------------+ _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
