Long story short

UrlDispatcher.add_routes returns nothing. I'd like to see a list of resources returned.

right now,

    def add_routes(self, routes):
        for route_obj in routes:
            route_obj.register(self)

What I want -

    def add_routes(self, routes):
        return [ route_obj.register(self) for route_obj in routes ]

Not sure route_obj.register returns a resource.

Expected behaviour

resources = router.add_routes(routes)

Actual behaviour

router.add_routes(routes) returns nothing

Steps to reproduce

This is an enhancement request.
