g'ah! I know it's no excuse, but I was on my way out from work when I posted, and for some reason got it stuck in my head that the outer ()* would only match repetition, i.e. 0 could be matched, but if you matched the leading 0, then the next match would have to be 0. Likewise if the pattern matched 11, it would have to match from the right side of the | again. *sigh* ++ zakb, I needed that. :P

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).

or How to display code and escape characters
are good places to start.
