witherable

witherable-class defines Filterable and Witherable class with instances. witherable provides indexed variants, optic-style generalised withers and extra instances.

Why not just fmap catMaybes . traverse f? Because wither can be defined to traverse the structure once. Also, its parametrity ensures that filtering works in a sane way. For more details, see also FilterableとWitherableについて
