I've been able to achieve the auto-numbering without relying on the internal implementation at all (with a limitation), with a single change to enumtype.new. My previous patch was slightly wrong - fix below as well. All existing tests pass. BTW, for mix-ins it's required that they have slots = () - might want to mention that in the PEP. What happens without _slots_ = () ?

Traceback (most recent call last): File "D:\Development\ref435\ref435.py", line 311, in class AutoIntEnum(AutoInt, IntEnum): File "D:\Development\ref435\ref435.py", line 138, in new enum_class = type.new(metacls, cls, bases, classdict) TypeError: multiple bases have instance lay-out conflict
