Hi everyone I hope you're doing fine, first I want to say this is crosspost: https://stackoverflow.com/questions/77557869/central-constructor-share-data-bless-hash-between-packages

I will tried to explain better here and find a solution to this problem, and I hope to learn something new.

I want to have access the latest data of parent constructor in all childs packages in $self.

why I want to do this:

In the constructor, I call external packages so I assigned the result to the hash reference constructor, inside child package I need that data and others config values of parent.

Possible solution:

I found a solution with rebless, and with this code, but I need to create variable and I have to call $self->{data}->{key} I want to avoid that . I wish I can call just like this $self->{key} inside child package without rebless.

Here a full working example, but have to call $self->{data}->{key}:

 
package Father;

my $store_data = { };

sub new {
  my $class   = shift;

  return bless { data => $store_data }, $class;
}

1;

package Daughter;

use parent qw(Father);

sub status {
  my $self   = shift;

  $self->{data}->{news} = 'bad';

  return $self;
}

sub other {
  my $self   = shift;

  return $self;
}

1;

package Son;

use parent qw(Father);

sub set {
  my $self   = shift;

  $self->{data}->{news} = 'good';

  return $self;

}

1;


use Daughter;
use Son;

my $self = Daughter->new()->status;
print Dumper($self);
$self = Son->new()->set;
print Dumper($self);
$self = Daughter->new()->other;
print Dumper($self);


$VAR1 = bless( {
                 'data' => {
                             'news' => 'bad'
                           }
               }, 'Daughter' );
$VAR1 = bless( {
                 'data' => {
                             'news' => 'good'
                           }
               }, 'Son' );
$VAR1 = bless( {
                 'data' => {
                             'news' => 'good'
                           }
               }, 'Daughter' );
