          Args:
              wait (typing.Union[int, float]): A numeric value that represents
                  the number of seconds that must pass before the callback
                  becomes available for execution. All given values must be
                  positive.
              identifier (typing.Any): The identifier returned from a call
                  to defer or defer_for.
  
          Returns:
              bool: True if the call is delayed. False if the identifier is
                  invalid or if the deferred call is already executed.
