I've been wondering if Data::Dumper is getting on towards its freshness date
Data::Dumper has been maintained by P5P alongside the core, so it's unlikely to go stale. It's just a bit unfortunate (IMHO) that its Useqq option is off by default - the other options I use in the linked post are mostly for "nicer" output, so as long as you write use Data::Dumper; $Data::Dumper::Useqq=1;, the module is fine. Data::Dump has prettier output by default, but if you look at its issue list you'll see it's not perfect either. There are lots of other dumper modules out there. The main things to remember are that you want the modules to give unambiguous output (hence Useqq) and that these modules are debugging aids and not data serialization tools.

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).

are good places to start.
