It's because I am currently collecting ideas of how to conveniently add a fast hash to existing stuff in Sage. One idea was to add a fast __hash__ directly to the instances. But that seems to be a failing approach. Meanwhile I am more or less able to write a function FastHash, that takes a class as an input and returns "the same" class, but with a Cythonised cached hash. I guess, on the level of instances, self.__class__ = FastHash(self.__class__) might work, and on the level of classes, FastHash may be a metaclass. But I have to learn about metaclasses first.
