Good signature.  The multi-line effect is a nice change from the usual single liner.

Here's a quick stab at shortening it:

s;;5776?12321=10609$d=9409:12100;;s;(\d*);push@_,$1;eg;map{warn chr sq
+rt,$/}@_

Once it was under 80 chars I declared success, but there's surely others who will shorten it further ...
