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:

{* ../../docs_src/python_types/tutorial009c_py39.py hl[1,4] *}

O parâmetro `name` é definido como `Optional[str]`, mas ele **não é opcional**, você não pode chamar a função sem o parâmetro:

```Python

           * technique previously used by BigIntegerMath: maintain separate numerator and
           * denominator accumulators, multiplying the fraction into result when near overflow.
           */
          for (int i = 2; i <= k; i++, n--) {
            if (numeratorBits + nBits < Long.SIZE - 1) {
              // It's definitely safe to multiply into numerator and denominator.

		s.writeErrorResponse(w, err)
		return false
	}

	diskID := r.Form.Get(storageRESTDiskID)
	if diskID == "" {
		// Request sent empty disk-id, we allow the request
		// as the peer might be coming up and trying to read format.json
		// or create format.json
		return true
	}

	storedDiskID, err := s.getStorage().GetDiskID()
	if err != nil {
		s.writeErrorResponse(w, err)
		return false

       * that behavior is undefined when the backing map is modified through another API. (It even
       * permits us to throw IllegalStateException. Maybe we should have done that, but we probably
       * shouldn't change now for fear of breaking people.)
       *
       * If the entry is still in the map, then updateIndex ensured that `index` points to the right
       * element. Because that element is present, uncheckedCastNullableTToT is safe.
       */

     * followed by those lines.
     *
     * HTTPS responses also contain SSL session information. This begins with a blank line, and then
     * a line containing the cipher suite. Next is the length of the peer certificate chain. These
     * certificates are base64-encoded and appear each on their own line. The next line contains the
     * length of the local certificate chain. These certificates are also base64-encoded and appear

Aber in den Fällen mit wirklich schwerwiegenden Fehlern, die den laufenden **Prozess** zum Absturz bringen, benötigen Sie eine externe Komponente, die den Prozess **neu startet**, zumindest ein paar Mal ...
