[swift-evolution] Pre-proposal: Convert reference params to tuples

[Tino Heth]

Imho it sounds good, but I rarely encounter situations where I would benefit from the proposed change… and afair "out" is an Objective-C addition, so there would be no improvement for plain C.
So I would surely find use for the automatic conversion, but if I would have to write it on my own, I'd rather take the lazy solution and stick with the status quo and write wrappers.
