Any reason why `@discardableResult` can't be applied to closures?

In what sense, then, is @discardableResult a type-level attribute under this scheme? Isn’t this indistinguishable in behavior from @discardableResult being an attribute of the binding?

Perhaps Max means that in the following simplified example:

func foo() -> Int { 0 }
@discardableResult func bar() -> Int { 0 }

let x = foo
x() // Warning: Result of call to function returning 'Int' is unused

let y = bar
y() // Warning: Result of call to function returning 'Int' is unused

if discardableResult is moved to the type attribute the warning for y() would disappear (which makes total sense to me). @Max_Desiatov, correct me if I got you wrong.
