:: Monoid_a _ => _ a -package:pandoc-plot

look :: forall w (sig :: (Type -> Type) -> Type -> Type) m . Has (Accum w) sig m => m w
fused-effects Control.Effect.Accum
Look up the previous accumulation 
runAccum w look = return (w, w)
runAccum w (look >>= continuation) = runAccum w (continuation w)
cutfail :: forall (sig :: (Type -> Type) -> Type -> Type) m a . Has Cut sig m => m a
fused-effects Control.Effect.Cut
Fail the current branch, and prevent backtracking within the nearest enclosing call (if any). Contrast with empty, which fails the current branch but allows backtracking. 
cutfail >>= k = cutfail

cutfail <|> m = cutfail
empty :: forall (sig :: (Type -> Type) -> Type -> Type) m a . Has Empty sig m => m a
fused-effects Control.Effect.Empty
Abort the computation. empty annihilates >>=: 
empty >>= k = empty
ask :: forall r (sig :: (Type -> Type) -> Type -> Type) m . Has (Reader r) sig m => m r
fused-effects Control.Effect.Reader
Retrieve the environment value. 
runReader a (ask >>= k) = runReader a (k a)
get :: forall s (sig :: (Type -> Type) -> Type -> Type) m . Has (State s) sig m => m s
fused-effects Control.Effect.State
Get the current state value. 
runState a (get >>= k) = runState a (k a)
autoTC :: forall t a . Auto (TyPred t) a => t a
decidable Data.Type.Predicate.Auto
A version of auto that "just works" with type inference, if the predicate is a type constructor.
exitFailure :: MonadIO m => m a
relude Relude.Lifted.Exit
Lifted version of exitFailure. 
>>> exitFailure
*** Exception: ExitFailure 1
exitSuccess :: MonadIO m => m a
relude Relude.Lifted.Exit
Lifted version of exitSuccess. 
>>> exitSuccess
*** Exception: ExitSuccess
exitFailure :: MonadIO m => m a
rio RIO
Lifted version of "System.Exit.exitFailure". @since 0.1.9.0.
exitSuccess :: MonadIO m => m a
rio RIO
Lifted version of "System.Exit.exitSuccess". @since 0.1.9.0.
exitFailure :: MonadIO m => m a
universum Universum.Lifted.Env
Lifted version of exitFailure.
exitSuccess :: MonadIO m => m a
universum Universum.Lifted.Env
Lifted version of exitSuccess.
exitCleanly :: MonadIO m => m a
hdaemonize System.Posix.Daemonize
Use this function when the daemon should terminate normally. It logs a message, and exits with status 0.
pending :: (HasCallStack, MonadIO m) => m a
sandwich Test.Sandwich.Expectations
Throws a Pending exception, which will cause the test to be marked as pending.
