in reply to Golf code in perl
Not specifically answering your question, but you seem to have become addicted to the competitive aspect of code golf. Though currently retired, I've experienced first-hand how addictive it can become, how you find yourself shaking your fist in fury at someone you don't know, from the other side of the world, who just had the temerity to pass you on the code golf leaderboard! :)
BTW, tybalt89, who answered your post with the 44 character solution, is mentioned in some of the links below and is one of the all-time golfing greats, and yes he is on the other side of the world to me, and yes he used to regularly pass me on the Perl golf leaderboard ... though I didn't shake my fist in fury at him because I knew how good he was and expected it; I shook my fist most often at `/anick, who I expected to beat, but sometimes didn't.
