kotlinlang

When working on a new Kotlin project with Arrow I get the feeling that I have to choose between using `Option` or Kotlin's nullable types (with `?`) to denote absences.

Would it not be great that these two could somehow be integrated together so that nullable types (with `?`) would behave as Arrow's Option?
I.e. provide the same methods and typeclass instances for `?` types as for Option types and allow them to be used anywhere where an Option could? Or is there some fundamental fault with this idea?
