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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
