My problem with this code is not aesthetics. This logic is too deeply nested, by the time you hit the last conditional there is way too much going on[1].
Perl makes it especially nice to flatten logic due to RHS conditionals, eg "x++ if y;". Here is my two minute flattening job[2], it prob has syntactic errors but you get the gist.

Seriously though, I use maps and greps a lot now, often chained to transform a data structure from one type to another. I'm annoyed when I have to drop to a for(each) loop.
