[swift-evolution] Pitch: Automatically deriving Equatable/Hashable for more value types

[Tony Allevato]

Just to update everyone on the thread—it took a little longer than I'd
hoped to get the kinks out, but I finally have the implementation up as a
PR: https://github.com/apple/swift/pull/9619

Hopefully there's still enough time to get the proposal reviewed, make any
changes needed, and get this into Swift 4!
