[swift-evolution] [Pitch] Typed throws

[Adrian Zubarev]

Sure thing, but that’s not what I was asking about. Kevin made a protocol that conforms to Error where all the his enums conformed to MyError protocol. That way we’re losing all enum cases and are not really a step further as before.

Is the throwing type always a protocol? In your example it is, but is this going to be always the case?

I think right now, there’s a bit of compiler magic in that you can only throw something that conforms to `Error`.
