> This solution is a bit wordy

I'm not a Haskell programmer, but I understood it. It looks like an ML language but with a lack of | and * for guards and tuples. I like your solution a lot.

The main features which allows you to code this solution in such a safe way are the Maybe and Either types. It's high time OO programmers - and OO programming languages - learn the lessons FP languages have taught us and include these constructs in the standard library. They're just so much cleaner than the usual alternatives (nullable types, checked exceptions) and there's no reason they can't be defined as small objects.

I'm going to be That Guy and suggest you give Rust a try. It's got the best of imperative and functional mixed in.

The implication being that OO is the same thing is imperative? I'm in strong disagreement with that!

I've tried to learn rust a few times, but never with much tenacity. It's on my list because it seems to hit a good point wrt expressiveness and performance.

Not what I meant, no.

In oversimplified terms, Rust has objects but not classes. It skews more toward: - from a C dev's perspective: data-driven design - from a Haskell dev's perspective: typeclasses and ADTs
