[swift-evolution] Revisiting SE-0110

[Nevin Brackett-Rozinsky]

One possibility is to make parentheses consistently meaningful in closure
argument lists, so that “(a, b)” would exclusively mean “there is one
parameter of tuple-type, which is being destructured”, while “a, b” without
parentheses would exclusively mean “there are two parameters”.

That way you can destructure a tuple parameter if you wish (by using
parentheses) or you can leave the tuple intact (by listing a single
identifier without parentheses).
