Comment (by vbraun):
Often you can have normal forms on general grounds, so IMHO would be
reasonable to just make `CanonicalRepresentation` a part of vector spaces
and such. Thats why I said we shouldn't have to do it for every parent by
hand. For most parents the `hash(repr(element))` is a good enough hash
function. Sure you could make it faster by an overall constant factor, but
its still gives you O(1) associative containers.
