Haskell is most likely quite different from any language you've ever used before. Compared to the usual set of concepts in a programmer's mental toolbox, functional programming offers us a profoundly different way to think about software. In Haskell, we de-emphasise code that modifies data.
A Good Solution: Constraint Based Generics and Parametric Polymorphism. I think the best generic programming system we have right now is what both Rust and Haskell use. This is often referred to as a system of constrained types. In Haskell, this system is called type classes, and in Rust it's called traits.
