Perl Module to parse any other Perl script/module to fetch stats about data-structures

[Parag Kalra]

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
