Meh.
Not nagging at you personally obviously, but I've found that the use of strict and warnings to be more of a pain in the ass than anything generally useful or even pragmatic.. Yeah, I know, blasphemy. I'm far from a god of Perl, but, imho, if you willfully choose to carry the use strict boulder around your neck, you end up unnecessarrily doubling your development time chasing down bugs that aren't really bugs; It's time spent satisfying an unnecessary and optional hurdle, since the code already works as designed. I often wonder if half the stuff I do really justifies the time required to do it....For quickie scripts (like this one) I usually don't bother.
Doing something collaborative, however, or mission-critical production level stuff, would be a different story obviously. In those circumstances, i'd consider it useful.
Maybe i'm just resentful. :) Thanks for the writeup, anyhoo. :)
