alternative-io-0.0.0: IO as Alternative instance
Lifted IO like Alternative instance. Due to technical limitation,
Lifted IO is not an instance of Alternative. (<||>) is provided
(<||>) :: MonadBaseControl IO m => m a -> m a -> m aSource
If the left IO monad of (<||>) causes an error or goNext is used,
the right IO monad is executed.
goNext :: (MonadIO m, MonadBase IO m) => m aSource
Go to the next IO monad by throwing AltIOLiftedGoNext.
runAnyOne :: (MonadIO m, MonadBaseControl IO m) => [m a] -> m aSource
Run any one lifted IO monad.
