Definitely, and I actually use that a fair amount, and Hash::Util's functions were part of the inspiration for this. The advantage of this module is that it saves you two characters ;-) (they're a little slower to type on a German keyboard too...) One of the disadvantages is that method calls don't interpolate into strings.
(Hmmm, maybe I could to add a -lock option to additionally lock the hashref's keys, so the hash can be used safely in both ways... Update: Done!)

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).
