Mergesort is more complex to implement I think, though not massively so. Perl did once use quicksort, but it was changed in 5.8. The old sorting algorithm can be enabled using:

use sort '_quicksort';

Memory leak... indeed. Is it too early to be getting sick of pre-5.16 Perls? In practice you'd probably give the sub a name so this wouldn't be an issue.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
