extension Dictionary {
    init<S: Sequence where S.Iterator.Element == (Key, Value)>(pairs: S) {
        self.init()
        for (key, value) in pairs {
            self[key] = value
        }
    }
}

let foo = ["Lorem", "ipsum"]
let bar = ["dolor", "sit"]
let baz = zip(foo, bar)
let qux = baz.lazy
    .map({ ($0.uppercased(), $1.uppercased()) })

print(Dictionary(pairs: baz))
print(Dictionary(pairs: qux))
