* The members of Result are isSuccess, isFailure, exceptionOrNull, getOrNull * The rest of API is implemented via inline-only extensions * There are two internal functions to hide detailed mechanics of an internal Result.Failure class: createFailure and throwOnFailure * Result.toString is explicit: either Success(v) or Failure(x) See KT-26538
