Moreover, for some data structures, the __cmp__ approach can be
expensive. For example, if you're comparing sequences of any kind,
and you know that the comparison is for == or !=, you have your answer
immediately if the sequences differ in length. If you don't know
what's being tested, as you wouldn't inside __cmp__, you may spend a
lot more time to obtain a result that will be thrown away.
