The zippo package
This light-weight library provides a basic, but fully-type-checked zipper implementation, suitable for any algebraic data structure. Our implementation has no notion of "left" and "right", and instead uses lenses (from the yall package) to indicate directions to "navigate down to".
For a similar approach with many more features, but less type-safety see pez.
