Another problem I have encountered whilst creating my set of modules. Say I have my set of modules that are named as follows:

Module::Main
Module::Section1
Module::Section2

Now, let's say that I have the following code in index.pl:

#!/usr/bin/perl -w
use strict;

use Module::Main;
my $REQ = new Module::Main;
$REQ->init();
$REQ->start_it();

[download]
This is the start of it. Now, a couple of other modules are added to the mix...

Module::Main contains something like the following:

package Module::Main;

sub new {
  my $class = shift;
  my $self = {};
  bless ($self, $class);
  return $self;
}

sub init {
  my $self = shift;

  $self->{SEC1} = new Module::Section1;
  $self->{SEC2} = new Module::Section2;
  return 1;
}

sub start_it {
  my $self = shift;

  $self->{SEC1}->do_something();
  return 1;
}

And now, let's say that Module::Section1 contains something like this:

package Module::Section1;

sub new {
  my $class = shift;
  my $self = {};
  bless ($self, $class);
  return $self;
}

sub do_something {
  my $self = shift;

  =cut
    HERE! Now I need to access $REQ->{SEC2}->method();
    The problem? $self now contains the object specific
    to Module::Section1 (ie: $REQ->{SEC1}, not to $REQ.
    So I can't do $self->{SEC2}->method(). I could always
    change the my() declaration in index.pl to an our() and
    then use $::REQ->{SEC2}->method(), but this just
    defeats the purpose of using OO programming! Besides,
    this would require that the variable be named $REQ and
    not anything else. I could always pass a reference to
    $REQ to everything subroutine/method, but that just
    seems extremely messy and bad programming style.

    So how can I accomplish this?
