I've never had reason to question where or how I use sort/reverse until now. Given the following code (note I'm doing string sorting):
my @keys = qw(
    3242_38
    2313_44
    3242_37
    3518_38
    3242_49
    3518_44
    );

map { print "$_\n" } reverse @keys;

I would expect the following results:
3518_44
3518_38
3242_49
3242_38
3242_37
2313_44

But instead I get:
3518_44
3242_49
3518_38
3242_37
2313_44
3242_38

Which is neither sorted forward or reverse or the original order. If I change 'reverse' to 'sort' I get perfectly good sorted output. So why does 'reverse' put the wammy on my results? I must be missing something incredably simple here :(

UPDATE - If it was a snake it would have bit me. Excuse me while I go whack my head with a board for a few hours...
