Data.Functor.Reverse
Description
Making functors whose elements are notionally in the reverse order from the original functor.
- newtype Reverse f a = Reverse (f a)
- getReverse :: Reverse f a -> f a
Documentation
The same functor, but with Foldable and Traversable instances
that process the elements in the reverse order.
