[swift-evolution] [Proposal] function "return" optional keyword.

[Craig Cruden]

When writing short functional code in a function it would be nice if the return keyword were an optional keyword. 

Just return the last evaluated expression.


i.e.

    func flipFunc<T, U>(arg1: T, arg2: U) -> (U, T) {
        (arg2, arg1)
    }


The keyword return would still be there for breaking out of a function.
