Along with Hug (as Hug is based on Falcon) inspired **FastAPI** to declare a `response` parameter in functions.

Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.

    Headers headers = Headers.of(name1, value1, name2, value2, ...).

 *  New: `Response.isSuccessful()` is a convenient API to check response codes.
 *  New: The response body can now be read outside of the callback. Response
