Nothing about MaybeT monad: a more concise way?

I am experimenting with monad MaybeT

, in particularMaybeT Identity String

import Control.Monad.Trans.Maybe
import Control.Monad.Identity
import Data.Maybe

main :: IO ()
main = putStrLn . show . runIdentity . runMaybeT $ maybeGetString

maybeGetString :: MaybeT Identity String
maybeGetString = return "first" >>
                 maybeTNothing >> 
                 return "second"

maybeTNothing :: MaybeT Identity String
maybeTNothing = MaybeT $ return Nothing

      

        
        
        
      

    

The experiment for the equivalent MaybeT

Nothing

seems MaybeT $ return Nothing

to feel a bit verbose, and it seems surprising to me that I have to explicitly use the constructor MaybeT

.

Is there a shorter / more convenient / clearer way to write Nothing

in a monad MaybeT

?
