Can you please give your definition of the Parser and ParserT type
constructors?  My guesses are:

    data State		=3D ...
    data Message	=3D ...
    data Accept a	=3D Fail Message | Empty | Ok State a
    data Decide a	=3D Rejected | Accepted a

    data Parser a	=3D Parser (State -> Decide (Accept a))
    data ParserT m a	=3D Parser (State -> m (Decide (Accept a)))

I wonder if it wouldn't be possible to redefine ParserT as

    data ParserT m a	=3D Parser (State -> m (Decide (m (Accept a))))

?
