Do we have any Perl module which can parse any other perl script (or module) and fetch information like total number of arrays being used, total number of hashes, total number of scalar variables etc and size information (like total elements, total keys etc) for each data structure in that perl script or may be another perl module Thanks, Parag

Even my own internal traces didn't follow single elements. I would suspect that this would be something that would have to run against the file itself, even prior to compile. Curious task.

Re: Perl Module to parse any other Perl script/module to fetch stats about data-structures
By data-structures being used, I mean the data structures that are actually *declared* in the script. And is it possible to find at least the data-structures stats of the current script that is getting executed if no parser is available. For example if I have a big script or module and if I want to find total arrays, hashes and variables declared in that script. Is there any special variable where this info is stored.
