So do you mean doing something like this:
{{{#!python
class DummyFactory(UniqueFactory):
def __call__(self, *args, **kwds):
return factory_function(*args, **kwds)
def get_object(self, the, ..., args):
return OriginalFactoryInstance.get_object(the, ..., args)
}}}
and `DummyFactory` would become the object in the global namespace?
