If $foo is an object, you shouldn't be peeking at $foo->{name} anyway; write an accessor so that you can do $foo->name.
Funny you should mention that. That's precisely what I was trying to do when I first saw the "DEFAULT block did not return a suitable reference to the hash dereference at ...". I decided it wasn't worth it a short time later, but it was starting to look like I'd have to implement most of the class inside one of Contextual::Return's METHOD { ... } blocks.
You're spot on, though. If I use anything, it'll probably be Want.

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).
