Post #1421577

I had a sneaking suspicion that the single, collapsed async trick might be an (isolated Self) parameter in this week's @pointfreeco episode, having used it in my Unimplemented mock-generating macro. Felt good seeing it confirmed! It’s an unbelievably useful trick – and it gives you synchronous access to the actor's state for the duration of the closure (with just the `await` to run the method)
