An Optional is an optic that allows seeing into a structure and getting, setting, or modifying an optional focus. It combines the properties of a Lens (getting, setting, and modifying) with the properties of a Prism (an optional focus). An Optional can be seen as a pair of functions: - get: S => Optional[T] - set: (T, S) => S A Optional could also be defined as a weaker Lens and weaker Prism
