[swift-evolution] Making `.self` After `Type` Optional

I personally don't mind the trailing `.self` but it does seem strange that you
need that, or not, based on the number of parameters. I definitely think it
would be nice to unify this one way or the other.
Another interesting consideration I ran into just today is trying to use `self`
as a `#selector` in Swift 2.2. Swift happily converts:
In some cases. But because of `.self` referencing the type, this doesn't do what
you'd expect. Which is an interesting edge case.
