in reply to Globals with Strict

You have three options

  1. the vars pragma to declare package level variables
  2. available in perl5.6+, our which declares a package level and also creates lexical variable aliased to the package variable
  3. fully qualify the variables with their package name

Which you can implement like so 

use vars '$config';

our $config;

$Your::Package::config;

    File-scoped lexicals are globally-scoped to anything in that file. our is only really useful when dealing with application-globals - things that will be used in more than one file. (@ISA, @EXPORT_OK, and $VERSION come to mind.) That's the reason why my is singularly possessive and our is plurally possessive. I personally think that our is misused in 99% of its usage.
