[Pitch] Introduce user-defined dynamically "callable" types

Instead of baking in hard coded support for one language or the other, I’m preferring to add a few small but general purpose capabilities to Swift. This is the first, which allows a Swift type to become “callable”. The proposal is here: https://gist.github.com/
