[New-bugs-announce] [issue43744] enum: Adding a var named _anything__ raises IndexError

[Matthias Urlichs]

New submission from Matthias Urlichs <matthias at urlichs.de>:

While checking out the Enum implementation I noticed that this code snippet results in an IndexError.

I have no idea which error or warning (if any) this should generate instead. Opinions?

    import enum
    class duh(enum.Enum):
        _duh__ = "moo"
