before handlers are called before all requests, but you don't have to do 
anything if the request isn't one you're interested in.

e.g.

    before sub {
       return if request->path_info !~ m{^/private/};
       # Authentication stuff here
    };

Is that any use?

Of course, that means the list of which routes require authentication is kept 
separately to the route declarations themselves, which might not be what you 
want.
