[swift-evolution] Enums and Source Compatibility

[Rod Brown]

Hi Jordan,

I think this is a great update to the proposal. The scope is small, which is good, and it clearly speaks about it’s reasoning about some of the concerns some people have.

A big thumbs up from me! 👍

I'll update the proposal today to reflect that, though I still want to keep both the "nonexhaustive" and "exhaustive" keywords for Swift 4 compatibility for now (or whatever we end up naming them). The compatibility design is a little less ambitious than Brent's; as currently proposed, Swift 4 mode continues to default to 'exhaustive' all the time, even in the actual Swift 5 release.
