[swift-evolution] Type-annotated throws

[Tino Heth]

I'm quite skeptical here (Java has already been mentioned…), but if it's done, I'd vote for removing ErrorType:
This empty protocol always felt a little bit odd to me, and when each function has information about what errors to expect, imho there is absolutely no benefit associated with conformance.
Even now, it's not that much — or does anyone actually consult a list of conforming types for error handling?
