```
I find myself wanting sequence-polymorphic pattern matching of…

The library has `itraversed` to give an `IndexedTraversal` for any `TraversableWithIndex`.
It would be also nice to have `ifolded` and `imapped` to give an `IndexedSetter` for any `FunctorWithIndex…

This discussion started at #126, where we discussed a proposed linear `Foldable` implementation and the fact that it is not implied by linear `Traversable`; and ended up concluding that what we need i…
