var dict = [Int:Int?]()

dict[0] = (Int?).none // <--- sets to value nil

dict[0] = nil         // <-- removes

dict[0] = .none       // <-- same as previous, but more expressive

switch dict[0] {
case .none:
    Swift.print("Value does not exist")

case .some(let value):
    if let value = value {
        Swift.print("Value exists and is", value)
    } else {
        Swift.print("Value exists and is nil")
    }
