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.
