6. module Control.Applicative.PhantomState

   Phantom State Transformer type and functions.

7. type PhantomState s = PhantomStateT s Identity

   phantom-state	Control.Applicative.PhantomState

   Type synonym of PhantomStateT where the underlying Monad is the Identity monad.

8. data PhantomStateT s (m :: Type -> Type) a

   phantom-state	Control.Applicative.PhantomState

   The Phantom State Transformer is like the State Monad Transformer, but it does not hold any value. Therefore, it automatically discards the result of any computation. Only changes in the state and effects will remain. This transformer produces a new Applicative functor from any Monad. The primitive operations in this functor are:

   • useState: Performs effects. State is unchanged.
   • changeState: Changes state. No effect is performed.
   • useAndChangeState: Changes state and performs effects.
   Although useState and changeState are defined in terms of useAndChangeState:

   useState f = useAndChangeState (\s -> f s *> pure s)
   changeState f = useAndChangeState (pure . f)
   

   So useAndChangeState is the only actual primitive. Use runPhantomStateT (or runPhantomState) to get the result of a phantom state computation.
