Good Evening,

I do have a probably simple problem but I just can not fix it. Here is my point:

I have an own module (package) which is designed to create object-instances. In this package I have a "global" variable named %config. I put the word 'global' in quotation marks, because I think that's where my problem begins. I tried my, our and double-colon namespace syntax. This hash should be equal for all created objects. So far, so good. Every object is able to access %config. The package now contains a subroutine for reloading the (changed) config-file and storing its contents into %config after parsing. At this point the hash is either empty (or not accessible anymore?) for all object instances or did not change at all. That depends on how I declared the global hash. As you can see the sub-routine is the same as the one I call at the beginning of the package (to fill %config). I even tried almost-nonsense combinations in my desperation, but I am sure it is easily possible in any other way.

My program is very complex so I chose to post a simple (pseudo) takeout - The substantial is of importance for me. The _parse_file() sub-routine is purposely missing in order to keep clarity. 
package Foo;

use strict;
my %config = _fill_config();

sub new
{
   my $proto = shift();
   my $status = shift() || 'normal';
   my $package = ref($package) || $package;
   
   my $self = { status => $status };
   bless($self, $package);
   
   return $self;
}

sub change_config
{
   my $self = shift();
   return unless $self->{status} ne 'admin';
   %config = _fill_config();
}

sub _fill_config
{
   my %temp = _parse_file('config.cfg');
   return %temp;
}
