* Nas requisições, uma lista será lida, eliminando duplicadas e convertendo-a em um `set`.
        * Nas respostas, o `set` será convertido para uma `list`.
        * O esquema gerado vai especificar que os valores do `set` são unicos (usando o `uniqueItems` do JSON Schema).
* `bytes`:
    * O `bytes` padrão do Python.
    * Em requisições e respostas será representado como uma `str`.

## `Union` ou `anyOf`

Você pode declarar uma resposta como o `Union` de dois tipos, o que significa que a resposta seria qualquer um dos dois.

Isso será definido no OpenAPI com `anyOf`.

Para fazer isso, use a dica de tipo padrão do Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:
