I guess it is not required as stable in all cases. How about
new methods, #stable_sort and #stable_sort!?
That sounds good.
Yes, new methods would be fine. Perhaps if you use mergesort it should just
be called “mergesort”.
No, the algorithm name shouldn’t be in the method name; that means that
if they change the algorithm later, the name has to change. There are other
stable sorts besides mergesort, and a better one may even come along.
