orNull is a common API in Kotlin in contrast to Option.
If we are to deprecate Option as planned in #114 then we should also provide alternative APIs for the current Option APIs.

Option or ? is used to make unsafe APIs safe, or to indicate absence/terminal operations.

  • headOption -> firstOrNull
  • tailOption -> lastOrNull
  • mapFilter -> mapNotNull
