I personally think the best option is to have a Enumerable#stable_sort, rather than replacing the default behavior, since it's rarer for folks to need a stable sort, but it'd still be nice for it to be natively implemented when they do. I, however, don't have the forceful personality necessary to cajole something like that through. :) -- Morgan
