Many thanks Chris, for the extensive reply. There's some useful knowledge in it. My idea to call the base class reduce as the default fallback causes the problems: return return super(TestClass, self).__reduce__() If, following your suggestion, I replace that with: return self.__class__, (self.name,) it works fine. By the way, in the meantime I've played around with copyreg.pickle, and that code worked in all Python implementations I've tried it in. This code feels better too, because it is possible to simply use return self.__reduce__() as a fallback in it, because we're not touching the object's own __reduce__ in any way. Anyway thanks again Irmen -- http://mail.python.org/mailman/listinfo/python-list
