Acho que `Union[SomeType, None]` é mais explícito quanto ao significado.

É apenas uma questão de palavras e nomes. Mas essas palavras podem influenciar como você e sua equipe pensam sobre o código.

Como exemplo, veja esta função:

```python
from typing import Optional


def say_hi(name: Optional[str]):

   * future migration to {@code java.util.function} will not preserve this behavior.
   *
   * <p>As discussed above, prefer to use the method reference {@code Object::toString} instead,
   * though note that it is not serializable unless you explicitly make it {@link Serializable},
   * typically by writing {@code (Function<Object, String> & Serializable) Object::toString}.
   *

Für `Item-Input` ist `description` **nicht erforderlich**, es hat kein rotes Sternchen.

Aber für `Item-Output` ist `description` **erforderlich**, es hat ein rotes Sternchen.

	randInterval := func() time.Duration {
		return time.Duration(r.Float64() * 5 * float64(time.Second))
	}

	// To avoid all MinIO nodes reading the tier config object at the same
	// time.
	t := time.NewTimer(tierCfgRefresh + randInterval())
	defer t.Stop()
	for {
		select {
		case <-ctx.Done():
			return
		case <-t.C:

   *   <li>{@code false} in all other situations.
   * </ul>
   *
   * <p>This assumes that any non-null objects passed to this function conform to the {@code
   * equals()} contract.
   *
   * <p><b>Note:</b> this method is now unnecessary and should be treated as deprecated; use {@link
   * java.util.Objects#equals} instead.
