title: How can I make a static analysis call graph for Perl?
body: <p>I am working on a moderately complex Perl program. As a part of its development, it has to go through modifications and testing. Due to certain environment constraints, running this program frequently is not an option that is easy to exercise. </p>
  
  <p>What I want is a static call-graph generator for Perl. It doesn't have to cover every edge case(e,g., redefining variables to be functions or vice versa in an eval). </p>
  
  <p>(Yes, I know there is a run-time call-graph generating facility with Devel::DprofPP, but run-time is not guaranteed to call every function. I <em>need</em> to be able to look at each function.)</p>
