A non-empty comonadic list zipper

Why not another Zipper implementation?

A Hoogle search reveals various implementations of zippers.

The two that have the most similar feature sets to nonempty-zipper are list-zipper and non-empty-zipper.

list-zipper has a solid lens interface, and a ton of instances, however it's lacking documentation and an NFData instance.

non-empty-zipper is most similar to this package but it appears to be unmaintained (e.g. base has drifted).
