Perl Find Question

System

All of my perl does use strict. I have lots of scripts that need to find assets in a filesystem using various conditions - find all files, find all files containing some text, find all files with filenames matching some string, find all directories, find all files and directories, etc. I use File::Find::find for this but I would like to move the wanted function into a module with some more generic logic (pass a regex, etc.). But with strict on I don't know how to pass the array, regex, etc. to the find wanted subroutine in the module - the Perl compiler throws warnings about undeclared variables and won't let me install the module.

I hope this makes sense but I can clarify if needed. Hopefully someone has already resolved a similar problem.
