Yes, I can see that re-design is not an option for you at the moment, and I agree that modularising and adding use strict will aid both debugging and enhancement.

But why make it all so complicated? You can have lexical variables which are strict-compliant and still package-global — just use our instead of my:

# File: main.pl #! perl use Modern::Perl; use Foo; our $Id = 42; Foo::foo_id(); say 'In main, $Id is ', $Id; ... # File: Foo.pm package Foo; use Modern::Perl; sub foo_id { say 'In Foo, $main::Id is ', $main::Id; $main::Id = 17; } 1;

Output:

In Foo, $main::Id is 42 In main, $Id is 17

You can of course get fancier with @EXPORT, @EXPORT_OK, etc., but using the fully-qualified package names is probably a better strategy as it makes the trail of the global variables self-documenting.

Hope that helps,
