synopsis:           A data-type like Either but with an accumulating Applicative

  .
  A data-type like Either but with differing properties and type-class
  instances.
  .
  Library support is provided for this different representation, include
  `lens`-related functions for converting between each and abstracting over their
  similarities.
  .
  * `AccValidation`
  .
  The `AccValidation` data type is isomorphic to `Either`, but has an instance
  of `Applicative` that accumulates on the error side. That is to say, if two
  (or more) errors are encountered, they are appended using a `Semigroup`
  operation.
  .
  As a consequence of this `Applicative` instance, there is no corresponding
  `Bind` or `Monad` instance. `AccValidation` is an example of, "An applicative
  functor that is not a monad."
