I believe it's on the roadmap, but won’t make Swift 3.

See the Generics Manifesto: https://github.com/apple/swift/blob/master/docs/GenericsManifesto.md

When I read it before, I seem to remember it explicitly called out having an Array of Equatable as an example of something which should be allowed. I can’t see it there now, but I think it’s still the intention that it works some day.
