This is great news, as it will greatly simplify my application.
However, it doesn't work for me (also on 1.1901).

My app structure is

app.pl
lib/
   app.pm
   app/
      app1.pm

in app1.pm, I have

----
package app::app1;
use Dancer ':syntax';

use lib ('/Users/punkish/Sites/app/lib');
use app; # do I really need this and the line just above it?
use base 'app';

sub opts {
    my $self = shift;
    my $opts = $self->SUPER::opts();

    return {
        %{ $opts },
        app1 specific opts
    }
};
----

and, I get the following runtime error

Can't call method "SUPER::opts" on an undefined value at
/Users/punkish/Sites/app/lib/app/app1.pm line 16.

/Users/punkish/Sites/app/lib/app/app1.pm around line 16

13
14 sub opts {
15     my $self = shift;
16     my $opts = $self->SUPER::opts();
17
18     return {
19         %{ $opts },
