I see. Thanks. If I may then, perhaps there is prudence in having Ruby support 
documented non-overridable methods --at least in core. This would bring such 
"creatures" out of the shadows of exception into formal, documented 
acceptance. For instance, in the current case, Ruby could define #quicksort 
(or some such name) to bypass <=> and be non-overridable, while #sort itself 
could still use the reusable, albeit slower behavior. This would provided the 
best of both alternatives.
