I'm curious to know how I might give objects created by a parent class access to the data in the parent class:

{
  package parent 0.000001;
  use Moose;

  has 'changing_data' => (is => 'rw', isa => 'Str', default => '');

  sub set_data {
    my $s = shift;
    $s->changing_data('foo foo foo');
  }

  sub create_child {
    my $s = shift;
    my $data = shift;
    return child->new(changing_data => $data);
  }
}

{
  package child 0.00001;
  use Moose;
  extends 'parent';
}

my $p = parent->new();
$p->set_data;

my $child = $p->create_child($p->changing_data());
print $child->changing_data; 
$p->changing_data('bar bar bar');
print "\n";
print $child->changing_data;

# desired output
foo foo foo
bar bar bar

# actual output
foo foo foo
foo foo foo
