That kind of code will only work of there is just one return, and "" (or the hideous q{} from PBP) is the only possible alternative.
My example just simplifies the pre-emptive returns, and lives in the assumption that the default (after all the returns were done) still needs some real coding.
Personally, I like brevity, and both my code and yours are terse. I do not however think that your code is any clearer than mine. Both are clearer than the code of the OP though.
Enjoy, Have FUN! H.Merijn

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).
