On: Swift 3.0 Release Process

FYI, a third option is

    mutating func next() -> Element? {
        //...
        defer { pos += 1 }
        return pos
    }

Whether it's better is a matter of opinion

[stevetrewick → jayrhynas]

Nice. That's a beautifully idiomatic implementation of the original intent of post increment, if nothing else.

[jayrhynas → jayrhynas]

I just realized there's a small typo in the above, it should be

    return data[pos]
