/**
 * `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`, `Alternative`, 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.
