-- As an example for a higher order effect, consider a mutexed concurrent state
-- effect, where an effectful function may lock write access to the state while
-- making it still possible to read it:
--
-- > data MState s :: Effect where
-- >   MState :: (s -> m (s, a)) -> MState s m a
-- >   MRead :: MState s m s
-- >
-- > makeSem ''MState
--
-- We can now use an 'Polysemy.AtomicState.AtomicState' to store the current
-- value and lock write access with an @MVar@. Since the state callback is
-- effectful, we need a higher order interpreter:
--
-- > withResource ::
-- >   Member (Embed IO) r =>
-- >   s ->
-- >   (MVar () -> Sem (AtomicState s : r) a) ->
-- >   Sem r a
-- > withResource initial use = do

-- >   lock <- embed (newMVar ())
-- >   runAtomicStateTVar tv $ use lock
-- >
-- > interpretMState ::
-- >   ∀ s r .
-- >   Members [Resource, Embed IO] r =>
-- >   InterpreterFor (Scoped s (MState s)) r
-- > interpretMState =

-- | Variant of 'interpretScoped' that uses another interpreter instead of a

--
-- This is mostly useful if you want to reuse an interpreter that you cannot

-- implementation, 'interpretScoped' should be preferred.
--
-- /Note/: In previous versions of Polysemy, the wrapped interpreter was
-- executed fully, including the initializing code surrounding its handler,
-- for each action in the program. However, new and continuing discoveries
-- regarding 'Scoped' has allowed the improvement of having the interpreter be
-- used only once per use of 'scoped', and have it cover the same scope of
-- actions that @withResource@ does.
--
-- This renders @withResource@ practically redundant; for the moment, the API
-- surrounding 'Scoped' remains the same, but work is in progress to revamp the
-- entire API of 'Scoped'.
