Prism<S, A> is an alias of AffineFold<S, A> & Reviewer<S, A>. This means that a Prism operates exactly like an AffineFold with the added ability to reconstruct an S from an A. Examples of this are reconstructing an Option from a number, or reconstructing Either<string, number> from a string or a number.
