There is a several-month-old request to add aenum's [1] AutoNumberEnum
to the stdlib [2].

The requester and two of the three developers of Enum are in favor (the
third hasn't chimed in yet).

This new addition would enable the following:

        from Enum import AutoNumberEnum

        class Color(AutoNumberEnum):
            # auto-number magic is on
            Red
            Green
            Blue
            Cyan
            # magic turns off when non-enum is defined

Is it going to subclass Enum or IntEnum?

Enum.

Personally I would be quite
happy to never have to specify a value for enums ever again, but only if
they subclass Enum (since IntEnum is for compatibility with C stuff
where a specific value is needed I don't think users need to mess that
up by having the automatic numbering not work how they would expect).

If a user really wants that they can, of course, specify both 
AutoNuberEnum and IntEnum in the class header.
