No, you don't. Philip Eby has been working on various incarnations of generic functions for some time now. The only thing new with 3.0 is that they may be included in the standard library and parts of the rest of the standard library may use them to implement their features. Implementing generic functions themselves don't require anyone to convince python-dev of anything. http://python.org/pypi/simplegeneric/0.6 http://peak.telecommunity.com/DevCenter/RulesReadme -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
