    """Represents a generic HTTP status.

    Raise an instance of this class from a hook, middleware, or
    responder to short-circuit request processing in a manner similar
    to ``falcon.HTTPError``, but for non-error status codes.

    Args:
        status (str): HTTP status code and text, such as
            '748 Confounded by Ponies'.
        headers (dict): Extra headers to add to the response.
        text (str): String representing response content. Falcon will encode
            this value as UTF-8 in the response.
        body (str): Deprecated alias to :attr:`text`. Will be removed in a future Falcon version.
            :attr:`text` take precedence if provided.

    Attributes:
        status (str): HTTP status line, e.g. '748 Confounded by Ponies'.
        headers (dict): Extra headers to add to the response.
        text (str): String representing response content. Falcon will encode
            this value as UTF-8 in the response.
        body (str): Deprecated alias to :attr:`text`. Will be removed in a future Falcon version.
