Perhaps I'm being dense, but I think [c]hromatic's solution is overkill.
If I were writing (or re-writing) the entire code snippet from scratch, I'd agree. The point of replacing the switch statement was twofold. First, I don't like switch statements. I find them generally unperlish. Second, I wanted to replace just that code, in a local refactoring. Since it was a bugfix, I didn't want to change a bunch of other variables.
That left me with the question, "How do I update the values of these variables based on identifying keys, while maintaining the variable names?" It was shorter than reassigning the variables from the hash values.

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).
