My apologies, my coffee didn't sink in.  I thought you
were trying to redirect or make a link.  I don't think
you can do

$c->forward('world', [47,11])

since the docs say that arrayref goes into the
$c->request->args not  $c->request->captures.  It's
worth a try though.

Usually when I need this I'm redirecting instead of
forwarding since I want the URL in the browser to
change.

I'll check my code and see if I tried this somewhere.
