I see.

Since Dancer doesn't support the concept of creating a base class, and
then inheriting from it, how do I apply same settings to any route in
any package or sub-package?
Who told you you can use inheritance with Dancer packages? Dancer does 
nothing for you regarding inheritance, but that doesn't mean you can't 
do it yourself:

package FooApp::Base;

use strict;
use warnings;

use Dancer ':syntax';

sub opts {
     return { base => 42 };
}

get '/' => sub {
     "base opts : ".to_yaml(opts());
};

1;

package FooApp::Forum;

use strict;
use warnings;
use Dancer ':syntax';

use FooApp::Base;
use base 'FooApp::Base';

sub opts {
     my $self = shift;
     my $parent_opts = $self->SUPER::opts();
     return {
         %{ $parent_opts },
         forum => 34,
     };
}

get '/' => sub {
     "forum opts : ".to_yaml(FooApp::Forum->opts());
};

Tested with Dancer 1.1901 here, working.

Hope that helps,
