Data::Dumper is a case in point. It's a dumper for Perl variables, not data more generally. Can it be used as a drop-in replacement for PostgreSQL's pg_dump command? Not without loading that data into Perl variables first. Calling it "Variable::Dumper" would have been more descriptive.
Data::Dumper isn't an absolutely awful name for what it does, but there are better names that could have been chosen. Virtually all modules deal with data in some way; that doesn't mean that virtually all modules should sit in the Data:: namespace.

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).

or How to display code and escape characters
are good places to start.
