Only classes defined on the top level of a module are picklable (see http://docs.python.org/dev/py3k/library/pickle#what-can-be-pickled-and-unpickled ). The collections.namedtuple class factory function works around this limitation by setting the __module__ attribute of the created class, but I'm not sure if this solution can be used in this case.
namedtuple's trick only works when you assign the created class to a name at the module level. E.g.
MyFancyTuple = collections.namedtuple(...) The trick won't work for "anonymous" classes like the above use case. -- 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
