Value of the member, can be set in :meth:`~object.__new__`.

.. note:: Enum member values

Member values can be anything: :class:`int`, :class:`str`, etc. If
the exact value is unimportant you may use :class:`auto` instances and an
appropriate value will be chosen for you. See :class:`auto` for the
details.

While mutable/unhashable values, such as :class:`dict`, :class:`list` or
a mutable :class:`~dataclasses.dataclass`, can be used, they will have a
quadratic performance impact during creation relative to the
total number of mutable/unhashable values in the enum.

.. attribute:: Enum._name_

Name of the member.
