Routing question: I'm trying to support multiple "...

Routing question: I'm trying to support multiple "functions", each which has some custom resolution code, so I'm putting it in a route("{...}"). However some of the functions make use of Ktor routing like authenticate. This doesn't play nice with the routes because of ambiguity. If I put the authenticate and the handlers (w/ handle) in the same route, the authenticate is always taken. If I each handler in it's own route("{...}"), the sibling authenticate is never taken. And even without that, if I have two of the same authenticates at the same level (one is optional, one isn't), the first is always taken. Is there a way to do something like this, i.e. have routes with fallthrough the request isn't handled? I'm currently using a RouteSelector to do this, but it's quite a bit of overhead for something relative (at least conceptually) simple.

I want to have something like:

base/
    function1
    function2
    auth1/
        function3
    auth2/
        function4

where I do some resolution in the function* handlers and fall through to the others if that resolution fails. I.e. do some custom routing in the handle method.

A probably easier to implement alternative is a Route.route(selector: suspend RoutingResolveContext.(Int) -> RouteSelectorEvaluation, body: Route.() -> Unit) type method to do simple routing resolution based on a lambda. It's much easier to use than implementing a RouteSelector, and much more discoverable. The segment consumption API could probably be streamlined a bit if that's done, but even as is it's much nicer.
