It appears that you need some way to distinguish the end of input from, "that's all I have for now". You could use an empty Bytestring in S if you were careful that you maintained that, in normal processing, such a state doesn't arise. Otherwise, have a Maybe in your state and set it to Nothing when the input is exhausted. Then have combinators, like many, handle the EOF case sensibly.
