use strict;

This code is my first obfuscation, and my birthday present to me :-). It's based on a feature discovered by Ovid and mainly uses that one - in obvious and surprising ways I think.

It dosen't pass -w but it uses strict; (weird, eh ?), and it works at least with ActiveState Perl 5.005_03 (but reportedly not with 5.6)


Update: A spoiler/explanation is now available on my home node

More Update: I've got some reports that this obfuscation also works under ActiveState Perl 5.6, which I didn't test. Thanks to isotope and Tye.

    Very nice! I love it :) Never saw $~ before now.

    Just to clarify things, I think it was a bug, and not a feature that I uncovered. For those who are curious, you can read about it here.

    It works fine on my perl v5.6.0 built for sun4-solaris
