[swift-evolution] [Review] SE-0111: Remove type system significance of function argument labels

This mostly makes sense to me and it seems like mostly a good idea, but take this example:

func doSomething(x: Int, y: Int) -> Bool { return true }
let x = doSomething
x(10, 10)

Is it then legal to do this?:

x(blahblah:10, totallyOffTheWallLabelThatDoesNotAppearANYWHERE: 10)

That would seem odd to me. Maybe it could be useful, but it might also be *super* confusing. I’m not sure I have a suggestion as to what to do in a situation like this - but it doesn’t seem “right” to allow it.
