I have already created a model:

package BRK::Model::Menu;
use strict;
use warnings;
use base 'Catalyst::Model::Adaptor';

In the configuration file I have:

'Model::Menu' => {
  class => 'HTML::Menu::MoreLevels',
  args => do('/web/S/menu.pl'),

And the module HTML::Menu::MoreLevels create the menu object.

I load and store this object in the stash on each request in the Root::auto 
: Private method with:

$c->stash(menu => $c->model('Menu'));

But this would re-create the menu object on each request, and this takes 

The data structure of the menu is loaded only at startup by the do() in the 
configuration file, but then it is used on each request to re-create the 
menu object.
