Comment (by SimonKing):
The following (in which I use `UniqueRepresentation` on Partitions_n)
could also benefit from making `UniqueRepresentation` provide a cmp method
as well:
{{{
sage: P = Partitions(1)
sage: Q = Partitions(4)
sage: %timeit P==Q # this is how they do compare
625 loops, best of 3: 2.33 µs per loop
sage: %timeit P is Q # this is how UniqueRepresentation *should* compare
625 loops, best of 3: 248 ns per loop
}}}
