i haven't run it but i already see conflicts with nested $_. the
while(<>) will use $_ and so do the for loops. i wouldn't hazard a guess
as to what the code will do. i never run into that since i rarely use
$_. i use my vars on all loops and only use $_ where required
(map/grep/for modifier) or in one liners and such.
