## Optionaler Datei-Upload

Sie können eine Datei optional machen, indem Sie Standard-Typannotationen verwenden und den Defaultwert auf `None` setzen:

 * create {@code ListenableFuture} instances depends on how you currently create {@code Future}

	for cfgName, usersMap := range cfgToUsersMap {
		users := make([]madmin.OpenIDUserAccessKeys, 0, len(usersMap))

Pero luego obtenemos un `dict` en el parámetro `commons` de la *path operation function*.

Y sabemos que los editores no pueden proporcionar mucho soporte (como autocompletado) para `dict`s, porque no pueden conocer sus claves y tipos de valor.

Podemos hacerlo mejor...

## Qué hace a una dependencia

Hasta ahora has visto dependencias declaradas como funciones.
