I still think there is some possibility of relaxing the overlapping constraint problem but I’d rather have this feature in Swift 4 since it’s such a big win. The rules can always be relaxed later if we come up with a workable model.

I’ve been thinking about it for some time and regularly run into the problem it solves. Participated in the draft proposal thread as well.
