## Separated

```
interface Separated<A, B> {
readonly left: A
readonly right: B
}
```

Added in v1.7.0 (interface)

A `Separated`

type which holds `left`

and `right`

parts.

# Compactable

```
interface Compactable<F> {
readonly URI: F
/**
* Compacts a data structure unwrapping inner Option
*/
readonly compact: <A>(fa: HKT<F, Option<A>>) => HKT<F, A>
/**
* Separates a data structure moving inner Left to the left side and inner Right to the right side of Separated
*/
readonly separate: <A, B>(fa: HKT<F, Either<A, B>>) => Separated<HKT<F, A>, HKT<F, B>>
}
```

Added in v1.7.0 (type class)

`Compactable`

represents data structures which can be *compacted*/*filtered*. This is a generalization of
`catOptions`

as a new function `compact`

. `compact`

has relations with Functor, Applicative,
Monad, Plus, and Traversable in that we can use these classes to provide the ability to
operate on a data type by eliminating intermediate `None`

s. This is useful for representing the filtering out of
values, or failure.
