isn’t optional just replacing the null check with if(optionalRef.isPresent)?? i kinda get how this is safer, but clients can just call optionalRef.get() withou

  Optional is just signaling to the user that they should check. You could also do this in Kotlin and boom there goes the safety: fn nonNull(): String { val s: String? = null return !!s }
