| Summary : A data-type like Either but with an accumulating Applicative
|
Description :
< < http://i.imgur.com/uZnp9ke.png>>
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.
* `Validation`
The `Validation` 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. `Validation` is an example of, \"An applicative
functor that is not a monad.\".
