Manchmal benötigen Sie den Rückgabewert einer Abhängigkeit innerhalb Ihrer *Pfadoperation-Funktion* nicht wirklich.

Oder die Abhängigkeit gibt keinen Wert zurück.

Aber Sie müssen sie trotzdem ausführen/auflösen.

In diesen Fällen können Sie, anstatt einen Parameter der *Pfadoperation-Funktion* mit `Depends` zu deklarieren, eine `list`e von `dependencies` zum *Pfadoperation-Dekorator* hinzufügen.
