struct S { let n: Int }; extension S { init() { self.init(n: 1) } }

[1].flatMap(String.init)

[String.self].map { $0.init(1) }

[String.self].map { type in type.init(1) }

Observable.zip(obs1, obs2, resultSelector: MyType.init).asMaybe()

func foo() -> [String] {
  return [1].flatMap { String↓.init($0) }
}

Observable.zip(
  obs1,
  obs2,
  resultSelector: { MyType.init($0, $1) }
