Is dict_compare something added in 2.5? It is neither a builtin or dict method in 2.4.

In any case, this point is that dict ordering is as arbitrary as ordering, for instance, a dict and a string. Since Guido stopped the experiment of totally ordering all objects when complex nums were added, consistency suggests that all fake orderings be eliminated, leaving only the order of numbers, characters, and sequences of comparable objects.
