Elm and Ruby: A Different Approach to Nullability

Elm has an explicit type system, and I think particularly the way Elm is chosen to do it. It really has helped me rethink nullability and uncertainty and code just because it's right there staring you in your face. And a lot of work that I've done in Elm has been how do I separate the uncertainty from the certainty in my code? That's kind of something that now that I've had to do it explicitly in Elm, I can bring that to Ruby where it's much more implicit.
