We can disallow putting types in parentheses in single-element tuple
meaning.
For example, (Int) -> (Double) will be illegal because of (Double).
(Int) -> (Double) -> Bool will be legal, because parentheses mean function
type here.
(Int) -> () will be legal, because () means Void here.
This can be theme of a separate proposal.

What I really don't like is that we can have all this:
func f1() -> (Void) {..}
func f2(Void) -> ((Void)) {..}
func f3() -> (((()))) {..}
func f4(((Void))) -> (Void) {..}
func f5() -> ((Void)) {..}
func f6((())) -> (((()))) {..}
and all is equivalent for
func f() -> () {..}
