use sort '_mergesort'; (Score:1)
My favourite 5.10 moment was when I had finished writing a program [catalyst.net.nz] to do some re-ordering, and realising that I was sending in data to Perl's sort which was nearly already sorted - the worst kind of input to the quicksort algorithm - that Perl 5.10 has a pragma to make it use the sort I wanted. Nice.

Hasn’t mergesort been the default for a while now?
