Mypy sees enum members as integer

[phooijenga]

Summary

As of 2.0.0b7, mypy sees enum members as integers

Reproduction Steps

import betterproto

class Event(betterproto.Enum):
    START = 0
    STOP = 1

e: Event = Event.START

Expected Results

I expect the code to type-check without issues, as it does with 2.0.0b6.

Actual Results

test-enum.py:9: error: Incompatible types in assignment (expression has type "int", variable has type "Event")  [assignment]

System Information

betterproto 2.0.0b7 mypy 1.11.1

Checklist

• [X] I have searched the issues for duplicates.
• [X] I have shown the entire traceback, if possible.
• [X] I have verified this issue occurs on the latest prelease of betterproto which can be installed using pip install -U --pre betterproto, if possible.

Mypy isn't interpreting the bases list correctly. This isn't something we can fix (I've tried) if you want your code to type check use Pyright
