## Códigos de estado adicionales

Si quieres devolver códigos de estado adicionales además del principal, puedes hacerlo devolviendo directamente una `Response`, como una `JSONResponse`, y asignar directamente el código de estado adicional.

Por ejemplo, digamos que quieres tener una *operación de path* que permita actualizar ítems y devolver códigos de estado HTTP 200 "OK" cuando sea exitosa.
