title: How do I find which file Perl loaded when I use a module?
body: <p>in Perl, when I do <code>use &lt;module name&gt; &lt;ver&gt;;</code>, the system finds the <code>.pm</code> file for the library somewhere in the <code>@INC</code> path.</p>
  
  <p>Is there a reliable way to which file was actually loaded?</p>
