          :return: dict of the form: ``{<name>: <Parameter instance>, ... }``
          :rtype: :class:`dict`
  
          .. note::
  
              The :class:`Parameter` instances returned do not have a value, only
              a default value.
  
              To get a list of an **instance's** parameters and values, use
              :meth:`params` instead.
