The type signature above doesn't match the do block. It would either have to
be changed to something like:
translate :: Control.Monad.State.MonadState String m => m ()
(storing the string in the monad's state instead of using a monad which
returns it) or the do block could be replaced with the >>= operator as
below, to thread the returned string between the components of the "pipe":
translate :: Monad m => String -> m String
translate x =
return x >>=
createParseContext >>=
readToFirstIdentifier >>=
dealWithDeclarator >>=
consolidateOutput
