( #3333=superdoc: print w/ replies, xml ) Need Help??

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.
