Eu penso que `Union[SomeType, None]` é mais explícito sobre o que ele significa.

Isso é apenas sobre palavras e nomes. Mas estas palavras podem afetar como os seus colegas de trabalho pensam sobre o código.

Por exemplo, vamos pegar esta função:

 *     .maximumSize(1000)
 *     .create();
 * }</pre>
 *
 * <p>As a {@link Queue} it functions exactly as a {@link PriorityQueue}: its head element -- the
 * implicit target of the methods {@link #peek()}, {@link #poll()} and {@link #remove()} -- is
 * defined as the <i>least</i> element in the queue according to the queue's comparator. But unlike

		if err != nil || len(contentSHA256) == 0 {
			return ErrContentSHA256Mismatch
		}
	}

	// Verify 'Content-Md5' and/or 'X-Amz-Content-Sha256' if present.
	// The verification happens implicit during reading.
	reader, err := hash.NewReader(ctx, r.Body, -1, clientETag.String(), hex.EncodeToString(contentSHA256), -1)
	if err != nil {
		return toAPIErrorCode(ctx, err)
	}
	r.Body = reader
	return ErrNone
