[swift-evolution] Handling unknown cases in enums [RE: SE-0192]

[Jordan Rose]

I included that, but also I again don't think that's the correct design. There's a case where that's useful, but that shouldn't be the default, and I don't think it's important enough to do in Swift 5.

(https://github.com/apple/swift-evolution/pull/777) I think I've addressed everyone's feedback either in the proposal or on-list, if not necessarily convinced them. If there are no other major comments I'll let Ted know that it's ready to re-run on Monday.
