sweetblood has asked for the wisdom of the Perl Monks concerning the following question:

Is there a way to specify a stable sort? That is a sort where the non-keyed fields remain in natural order after the sort(fifo). I am of course presuming that Perl’s default behavior would be a more efficient unstable sort. If my assumption is incorrect then is there a way to specify an unstable sort to increase sorting performance?
