The things that make haskell and ocaml outwardly different are the pattern match syntax for function definitions, type signatures, the IO monad's slightly different syntax, all the category theory structures and their punctuation filled names, "<*>", and, you know, all that "theorems for free" and Curry-Howard stuff. But to get started, there's LYAH and (3)good tutorial books by Alejandro Mena, Simon Thompson and Graham Hutton, you can type expressions in to GHCi (the REPL) and see what types GHC infers, and you can, uh, encounter GHC error messages and warnings for the firs ttime.

this was written for getting an intuition about the syntax:
