* Doordat pydantic's datastructuren enkel instanties zijn van klassen, die je definieert, werkt automatische aanvulling, linting, mypy en je intuïtie allemaal goed met je gevalideerde data.
* Valideer **complexe structuren**:
    * Gebruik van hiërarchische Pydantic modellen, Python `typing`'s `List` en `Dict`, enz.

* `bool`
* `bytes`

### Tipos genéricos com parâmetros de tipo

Existem algumas estruturas de dados que podem conter outros valores, como `dict`, `list`, `set` e `tuple`. E os valores internos também podem ter seu próprio tipo.

Estes tipos que possuem tipos internos são chamados de tipos "**genéricos**". E é possível declará-los mesmo com os seus tipos internos.

Para eso, actualizamos el modelo de Pydantic `TokenData` con una nueva propiedad `scopes`.

Al validar los datos con Pydantic podemos asegurarnos de que tenemos, por ejemplo, exactamente una `list` de `str` con los scopes y un `str` con el `username`.
