> Why would you instantiate a class and call it result‽

Are you suggesting that the results of calculations should always be some sort of primitive value? It's not clear what you're getting hung up on here.

No, the result of a calculation could be a key value or list or other compound value - whatever the result is. I am getting hung up on deceptive naming. If you have a 'result', the calculation is done. You have a result.
