[Haskell-cafe] Why is "Cont" out of scope?

I am trying to use the Cont in Control.Monad.Cont but it seems to be

Prelude> import Control.Monad.Cont
Prelude Control.Monad.Cont> :t Cont

    Not in scope: data constructor `Cont'
    Perhaps you meant `ContT' (imported from Control.Monad.Cont)
Prelude Control.Monad.Cont> :t runCont
runCont :: Cont r a -> (a -> r) -> r
Prelude Control.Monad.Cont> :t ContT
ContT :: ((a -> m r) -> m r) -> ContT r m a
Prelude Control.Monad.Cont>

Any ideas?
