O `typing` também tem um atalho para declarar que algo pode ser `None`, com `Optional`.

Aqui vai uma dica do meu ponto de vista bem subjetivo:

* 🚨 Evite usar `Optional[SomeType]`
* Em vez disso ✨ use **`Union[SomeType, None]`** ✨.

 * {@linkplain Comparable natural ordering} also does not permit insertion of non-comparable objects
 * (doing so results in {@code ClassCastException}).
 *
 * <p>This class and its iterator implement all of the optional methods of the {@link
 * Collection} and {@link Iterator} interfaces. The Iterator provided in method {@link #iterator()}
 * is not guaranteed to traverse the elements of the MonitorBasedPriorityBlockingQueue in

Aquí va un Consejo desde mi punto de vista muy subjetivo:

* 🚨 Evita usar `Optional[SomeType]`
* En su lugar ✨ **usa `Union[SomeType, None]`** ✨.
