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)
Enjoy
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.
