title: perl template toolkit TRY not working
body: <p>I have to test for the presence of file and then load. but it seems variable substitution inside () is not working:</p>
  
  <pre><code>&gt;     [% TRY %]
  &gt;        [% USE File("myfile.$userid") %]
  &gt;        [% INCLUDE "myfile.$userid" %]
  &gt;     [% CATCH File %]
  &gt;        [% INCLUDE "myfile.general" %]
  &gt;     [% END %]
  </code></pre>
  
  <p>can anyone advice a better way? or point to mistake?</p>
  
  <p>ty.</p>
