-- | Higher-order interpreter for 'Scoped' that allows the handler to use
-- additional effects that are interpreted by the resource allocator.
--
-- /Note/: It is necessary to specify the list of local interpreters with a type
-- application; GHC won't be able to figure them out from the type of
-- @withResource@.
--
-- 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:

{-# inline interpretScopedWith_ #-}

-- | Variant of 'interpretScoped' that uses another interpreter instead of a
-- handler.
--
-- This is mostly useful if you want to reuse an interpreter that you cannot
-- easily rewrite (like from another library). If you have full control over the
-- implementation, 'interpretScoped' should be preferred.
--
-- /Note/: The wrapped interpreter will be executed fully, including the
-- initializing code surrounding its handler, for each action in the program, so
-- if the interpreter allocates any resources, they will be scoped to a single
-- action. Move them to @withResource@ instead.
--
-- For example, consider the following interpreter for
-- 'Polysemy.AtomicState.AtomicState':
--
-- > atomicTVar :: Member (Embed IO) r => a -> InterpreterFor (AtomicState a) r
-- > atomicTVar initial sem = do
-- >   tv <- embed (newTVarIO initial)
-- >   runAtomicStateTVar tv sem
--
-- If this interpreter were used for a scoped version of @AtomicState@ like
-- this:
--
-- > runScoped (\ initial use -> use initial) \ initial -> atomicTVar initial
--
-- Then the @TVar@ would be created every time an @AtomicState@ action is run,
-- not just when entering the scope.
--
-- The proper way to implement this would be to rewrite the resource allocation:
--
-- > runScoped (\ initial use -> use =<< embed (newTVarIO initial)) runAtomicStateTVar
