1. evalRWS :: RWS r w s a -> r -> s -> (a, w)

   transformers	Control.Monad.Trans.RWS.Lazy

2. evalRWST :: Monad m => RWST r w s m a -> r -> s -> m (a, w)

   transformers	Control.Monad.Trans.RWS.Lazy

   Evaluate a computation with the given initial state and environment, returning the final value and output, discarding the final state.

3. execRWS :: RWS r w s a -> r -> s -> (s, w)

   transformers	Control.Monad.Trans.RWS.Lazy

   Evaluate a computation with the given initial state and environment, returning the final state and output, discarding the final value.

4. execRWST :: Monad m => RWST r w s m a -> r -> s -> m (s, w)

   transformers	Control.Monad.Trans.RWS.Lazy

   Evaluate a computation with the given initial state and environment, returning the final state and output, discarding the final value.

5. mapRWS :: ((a, s, w) -> (b, s, w')) -> RWS r w s a -> RWS r w' s b

   transformers	Control.Monad.Trans.RWS.Lazy

   Map the return value, final state and output of a computation using the given function.

   • runRWS (mapRWS f m) r s = f (runRWS m r
