• SR-1895 compilation warning for void result type

Issue Description:

If you compile the following code, a?.bar() has a return value of Void?. This doesn't result in an unused result warning when the statement is used on its own, but if used inside the ternary the warning Expression of type '()?' is unused shows up.

struct Foo {
  func bar() {}
}

let a: Foo? = nil
let b = true


b ? nil : a?.bar()  // Expression of type '()?' is unused
