You don't need the $first in your case:
before sub {
        if (not $cache->{statuses}) {
            $cache->{statuses} = ...;
            _load_cache();
        }
    }
Or perhaps simpler still:

    before sub {
        $cache->{statuses} ||= _load_cache();
    };
...
If you are not running in a CGI environment, then you should be able to
just do:
use Dancer;
    # put this in the file scope
    $cache->{statuses} = ...;
    _load_cache();
    # now declare routes
I believe the lines in the file scope will only get run once, running
in a persistent environment such as Plack servers or FastCGI.
Yep - that's how I'd do it.  That'll run at runtime once as the app is 
starting up, job done.

This is what I did in DancerJukebox to add some code to run at app startup to 
fork a new process to do stuff in the background, and it works a treat.
