It may be worth mentioning that pandas Categoricals are mutable and
zero-based:

Serialization to SQL and CSV is (also?) lossy, though:

Yes, and probably having an AutoNumberIntEnum would indeed be too much
magic in one place.
Anyway, it is easy to implement bitfield IntEnum without magic.
To be clear, I like the Ethan's original proposal.

Have you considered an option (keyword argument) to change this to

Why would you want that? I remind you that this descends from Enum, so

There is another issue relating to bitwise enums that deals with that.

I know this is of fairly limited interest, so this is just advertising

If you are someone who knows what CoInitializeEx is or why you may want
to call it, I'm interested in your feedback/concerns. Come and po

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(AutoNu
