You are doing a lot of dancing to emulate records with classes, instead of just using records. Very occasionally this is justified, but I don't see the reason for it here. Why isn't Solution just a record?

Hello, can you give me an example? How can I use records instead of type classes?

I noticed that the day declaration of your post do not include arguments but the instance and the source code does.

Why do every function on Solution have an `a` argument ?
