Making functors with an `Applicative`

instance that performs actions
in the reverse order.

NB: This module is only included in `lens`

for backwards compatibility with
`transformers`

versions before 3.0.

# Documentation

The same functor, but with an `Applicative`

instance that performs
actions in the reverse order.
