Hi Simon!
Replying to [comment:15 SimonKing]:
> A strange problem is the fact that `__cmp__` is inherited from
`CombinatorialClass`, even if I let `Partitions_n` inherit from
`UniqueRepresentation`. I have to check why this is the case - if it
inherits from `UniqueRepresentation`, then it should inherit ''both''
`__hash__` and `__cmp__` from it, and not only `__hash__`.
Thanks for investigating performance of UniqueRepresentation. Do not waste
time on making CombinatorialClass and UniqueRepresentation play perfectly
smoothly. CombinatorialClass is meant to dissapear anyway.
Cheers,
Nicolas
