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

  @GwtIncompatible // NavigableSet
  @Override
  @CheckForNull
  public E lower(E e) {
    return Iterators.<@Nullable E>getNext(headSet(e, false).descendingIterator(), null);
