I have to explicitly pass functions along with my values, maybe in a product type, or with a functor, or as an argument. Haskell is a mixed community / paradigm language too. I routinely program in "Braindead Haskell" (keep stuff simple and direct as much as possible). Funnily, in that programming style, using typeclasses for _all_ interface types is bad style. Instead, the Handle pattern [0] can be used. Which really is just shoveling functions in a product type. And imagine - it works worderfully. Everyone has to find their own style I guess.
