    We advise to use the Endo Monoid when you want to read a series of characters into a list. This means you use the difference lists technique in order to build the list, which is efficient.

    import Data.Monoid (Endo, appEndo, )
    import Control.Exception (try, )
    import qualified Control.Monad.Exception.Synchronous as Sync
    

    fmap (flip appEndo []) $ manyMonoidT (fromSynchronousMonoidT $ fmap (Endo . (:)) $ Sync.fromEitherT $ try getChar)
    

    If you want Lazy IO you must additionally convert getChar to LazyIO monad.
