Beside the fact that your code doesn't compile, there is another issue with the while loop, keys resets the iterator so each starts from the first pair each time. Your loop basically means that while you get the first key/value pair, print all the keys; which is an infinite loop.
Fletch is probably right and you probably just got this frankencode while trying different ways to debug, but FYI you should avoid using keys or values inside a while(each) loop.

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).
