De parameter `name` is gedefinieerd als `Optional[str]`, maar is **niet optioneel**, je kunt de functie niet aanroepen zonder de parameter:

```Python
say_hi()  # Oh, nee, dit geeft een foutmelding! 😱
```

De `name` parameter is **nog steeds vereist** (niet *optioneel*) omdat het geen standaardwaarde heeft. Toch accepteert `name` `None` als waarde:

```Python

            logger.debug("Initialize {}", this.getClass().getSimpleName());
        }
        stream(ComponentUtil.getFessConfig().getSearchDefaultPermissionsAsArray()).of(stream -> stream.forEach(name -> {
            defaultRoleList.add(name);
        }));
    }

    public Set<String> build(final SearchRequestType searchRequestType) {
        final Set<String> roleSet = new HashSet<>();

			err = globalSiteReplicationSys.PeerAddPolicyHandler(ctx, item.Name, nil, item.UpdatedAt)
