indexed-traversable-instances

More instances of FunctorWithIndex, FoldableWithIndex, TraversableWithIndex.

This package provides extra instances for type-classes in the indexed-traversable package.

The intention is to keep this package minimal; it provides instances that formely existed in lens or optics-extra. We recommend putting other instances directly into their defining packages. The indexed-traversable package is light, having only GHC boot libraries as its dependencies.
