I was looking over the dependency injection talk and am a bit confused about defining the interface dependencies with delegates. For instance, take the following interface:

interface NameFetcher<F> : Async<F> {
    fun fetchName(): Kind<F, String> = defer { just("bob") }
}

If I want an IO implementation, then IO conveniently provides an async delegate:

object IONameFetcher : NameFetcher<ForIO>, Async<ForIO> by IO.async() {}

However, I am confused in the case that I want a Try implementation. How can I satisfy the Async<ForTry> dependency?
