Whenever I seem to have this "search backwards" urge (not very often,
I admit), I without much thought just throw memory at it with
reverse($str) =~ /pat/
Or, if that's not the "search backwards" sense intended, then maybe
I'll throw time at it:
$str =~ /.*pat/
Sometimes I've also done
($str . $str) =~ /pat/
to effect a search that wraps around--kinda.
