```

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

                                    <label for="name" class="col-sm-3 text-sm-right col-form-label"><la:message
                                            key="labels.labeltype_name"/></label>
                                    <div class="col-sm-9">
                                        <la:errors property="name"/>
                                        <la:text styleId="name" property="name" styleClass="form-control"/>
