Swift: Fake ternary operator

infix operator < { associativity left }

func <<T : Comparable>(lhs: T, rhs: T) -> ((T, T) -> Bool, () -> T) -> Bool {
    return { (op: (T, T) -> Bool, value: () -> T) in
        (lhs < rhs) && op(rhs, value())
    }
}

func <<T: Comparable>(lhs: ((T, T) -> Bool, () -> T) -> Bool, rhs: @autoclosure () -> T) -> Bool {
    return lhs({$0 < $1}, rhs)
}

var x: Int = 5

if 1 < x < 10 {
    true
}
else {
    false
}
