Cannot load any enums

[gepz]

python=3.12.8
dill = ">=0.3.9,<0.4"
Example:

class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3
PATH = "test.pkl"
with open(PATH, "wb") as f:
    pickle.dump(Color.RED, f)
with open(PATH, "rb") as f:
    test = pickle.load(f)

Error in lib/python3.12/enum.py:544:

AttributeError: 'dict' object has no attribute '_member_names'

Oh god no 🤖💀 (previously reply to the LLM bot that is now gone)

I can reproduce this for all current versions of python 3.8-3.13 on the existing master branch of dill.

from enum import Enum
import dill as pickle

class Color(Enum):
    RED = 1 
    GREEN = 2
    BLUE = 3

red = pickle.copy(Color.RED)

Have you tested older versions of dill?

python 3.10 with dill 0.3.5:
AttributeError: 'dict' object has no attribute '_member_names'
python 3.10 with dill 0.3.2:
RecursionError: maximum recursion depth exceeded while calling a Python object

I noticed more recent versions of dill throw a Warning about Recursion... which would indicate that this has never been implemented before in dill. I'd have to verify that (generally, you can look here):

This has been an issue for a while, see #250
