I've been meaning to pick up either Haskell or OCaml for my next language. On the OCaml side, I see Cornell's free CS 3110 textbook recommended around here. Is there something similar on the Haskell side?
I learned by reading Haskell Programming from First Principles. Great book which covers most topics you'd need to know in order to write and read Haskell in the wild. Highly recommended
