I believe the situation is that we’re going to support Swift 3 syntax with a compiler flag, which frees us to make source-breaking changes for Swift 4. 

AFAIK, how we support this in the compiler isn’t determined yet.

That’s what I take from Ted’s email: https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20160725/025587.html
