Well, some code is certainly going to break such as this from warnings.py: assert isinstance(category, types.ClassType), "category must be a class" or this from traceback.py: if type(etype) == types.ClassType: stype = etype.__name__ else: stype = etype I hope to have a new patch (which makes PyExc_Exception new-style, but allows arbitrary old-style classes as exceptions) "soon". It may even pass bits of "make test" :) Cheers, mwh -- SPIDER: 'Scuse me. [scuttles off] ZAPHOD: One huge spider.
