The closest mention I could see to this problem and perhaps a clue is: The additional state of being matched with zero-length is associated with the matched string, and is reset by each assignment to "pos()".
So perhaps the issue is that the previous match succeeded - but did not advance pos, so when the /\G \z/ hits, pos doesn't advance and for some reason perl doesn't treat it as a successful match.
I'm still with davido. I think this is a bit of a bug - it introduces failure at a distance in custom parsing engines. Luckily for cases such as these pos == length happens to be true.
my @a=qw(random brilliant braindead); print $a[rand(@a)];

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).
