 * New: Protocol selection in MockWebServer.

 *         String s = in.next();
 *         if (s != null) {
 *           return s;
 *         }
 *       }
 *       return endOfData();

Si vous utilisez une bibliothèque externe qui communique avec quelque chose (une BDD, une API, un système de fichiers, etc.) et qui ne supporte pas l'utilisation d'`await` (ce qui est actuellement le cas pour la majorité des bibliothèques de BDD), alors déclarez vos *fonctions de chemin* normalement, avec le classique `def`, comme ceci :

```Python hl_lines="2"
