[swift-evolution] Opt-out for first unnamed parameter instead of opt-in

[Vanderlei Martinelli]

Hello.

I think this was discussed before somewhere and I do not know what the
conclusion was, but since we have this in the documentation:

func addSubview(_ view: UIView)

And we have to write this:

func addSubview(view: UIView)


Why we can not stay with the first one that is more consistent? The impact
is to replace declarations like:


func myMethod(something something: AnyObject)

With

func myMethod(something: AnyObject)


And replace:

func myOtherMethod(something: AnyObject)

With

func myOtherMethod(_ somethings: AnyObject)
