[swift-evolution] [Pitch] Brace omission for single-statement n-ary closures

[Patrick Smith]

I know there was more to what you were suggesting, but can I suggest removing the parentheses:

  let neg = [1, -2, 3].map{ -abs($0) }

  let ascii = words.flatMap{ $0.unicodeScalars.filter{ $0.isASCII } }
