Well, how about a hash ref whose keys are the names of all the modules in @INC? Would that meet your needs? This isn't in the documentation for my module, but you could do:
use HTML::Perlinfo::Modules;
my $hashref = (HTML::Perlinfo::Modules::find_modules("",1,\@INC))[1];
# Here are all the module names in @INC:
print "$_\n" for (keys %$hashref);
P.S. If you want even more information on those modules you can look into the values of those keys. Or just use Data::Dumper to see what's in that hashref.

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).
