title: How can I get a call stack listing in Perl?
body: <p>Is there a way I can access (for printout) a list of sub + module to arbitrary depth of sub-calls  preceding a current position in a Perl script?</p>
  
  <p>I need to make changes to some Perl modules (.pm's). The workflow is initiated from a web-page thru a cgi-script, passing input through several modules/objects ending in the module where I need to use the data. Somewhere along the line the data got changed and I need to find out where.</p>
