I don't know if your solution is correct. Many functional abstractions in Haskell, such as those that involve high level typeclass abstractions, make code more esoteric, and not more clear. However this is a tradeoff to make code more based in algebra and logical structure. This is more important than readability and conciseness.

There is a very strong argument that you shouldn't be using the high-level esoteric typeclass abstraction in Haskell, or even that you shouldn't be using Haskell for production programming. I say this as someone who likes Haskell a lot and wrote one of the top tutorials on the web for it. But if you run a business based on software, and your core value proposition is not the 100% provability of your code (eg. Galois), then readability and conciseness are absolutely more important than algebra and logical structure.

Very fair point. Thanks for replying.
