Re: [Haskell-beginners] Question about example in 'using do notation with Writer' section of LYH

what becomes of the string parts of the Writer monads

multWithLog keeps [String] and outputs Int to fully benefit from Writer [String] Int, you'd call e.g. runWriter or execWriter similar to other *State state out* monads, *m state out* lets you get/set/keep state as needed without passing it as an arg. *state* is there if you need it.
