[swift-evolution] ternary operator ?: suggestion

That's one fresh idea, and I like it. I can't find anything wrong with it, except that fn doesn't need to be an @autoclosure, just a Bool.

I believe the customary name for that function is iff.

I always wrap ?: in parenthesis for readability anyway.
