Oh, sort does remember you choices. It's not that it keeps a record, but it is remembered in the way the data is shuffled around. Otherwise, there wouldn't be O (n log n) sorts.

As for the segfaults, pre-5.6 perls used the qsort available in your C libraries. And that might segfault when given inconsistent choices. 5.6.x has its own quicksort, which will not segfault when given inconsistent choices. From 5.8 on, you can actually choice between mergesort (default) and quicksort.
