What's the benefit over attempting to hash() the object?

copy.deepcopy already has special case for int, string, and tuples
(including tuples that do and do not have mutable members) - could what
you need be accomplished by overriding __copy__ and __deepcopy__ in your
custom class to return itself if it is immutable?
