Then you could use a pseudo-object, for example storing your global variables in a lexical hashref in the const module, and have in that same module a get and a set functions to access the hash that you export. Something like this:
use strict; use warnings; use Exporter; our @ISA = 'Exporter'; our @EXPORT = qw(get set); my $private_hash_ref = {VAR1 => "one", VAR2 => "two"}; sub get { my $key = shift; return $private_hash_ref->{$key};} sub set { my ($key, $value) = @_; $private_hash_ref->{$key} = $value;}
And then in your main code or other module, you just use the set and get functions.
