Back in the day, Perl didn't have its own sort and just used the qsort() provided by the local C run-time library. I seem to recall that things like sort {[-1,1]rand(2)} could cause the algorythm to take forever to finish or even dump core.

Now a truely efficient sort should not be able to notice because it wouldn't do any more comparisons than it needed to. So perhaps the quality of Perl's sort is much higher than many of the qsort()s from back then.
