[swift-evolution] Deprecating Trailing Closures

I, on the other hand, cannot imagine how you would not see a difference between the two. The paren-less form is *far* more readable to me; when you put a parenthesis and a curly bracket next to each other, the curly bracket disappears and I can no longer see that the expression is a closure.

Swift generally doesn't mandate any particular style. I think this is a good time to continue that tradition.
