[swift-evolution] [Returned for revision] SE-0161: Smart KeyPaths: Better Key-Value Coding for Swift

\Vector -> Int seems like a more appropriate spelling there no?   The : is usually for is-a/conforms-to relationships, no?

And I agree that such a thing could be considered later and would make the world a better place.
