extend an IntEnum with documentation fails

[mvillion]

Following the example from https://stackoverflow.com/questions/28126314/adding-members-to-python-enums
but using IntEnum instead of Enum, yield an error.

from aenum import IntEnum
from aenum import extend_enum

class ColorHelp(IntEnum):
     _init_ = 'value __doc__'
     black = 0, 'the absence of color'

extend_enum(ColorHelp, 'white', 1, 'the presence of every color')

Traceback (most recent call last):

File "/tmp/ipykernel_13921/3054020738.py", line 1, in <cell line: 1>
extend_enum(ColorHelp, 'white', 1, 'the presence of every color')

new_member = _new(enumeration, *args, **kwds)
