También puedes declarar un cuerpo como un `dict` con claves de algún tipo y valores de algún otro tipo.

De esta manera, no tienes que saber de antemano cuáles son los nombres válidos de campo/atributo (como sería el caso con modelos Pydantic).

Esto sería útil si deseas recibir claves que aún no conoces.

Otro caso útil es cuando deseas tener claves de otro tipo (por ejemplo, `int`).
