```python class Foo: pass class Works(str, Foo, Enum): BAR = 'baz' class Fails(Foo, str, Enum): BAR = 'baz' ``` `Fails` fails to be created with an error: `TypeError: object.__new__(Fails) is not safe, use Fails.__new__()` See https://github.com/python/cpython/blob/e57f91a0f0d5700ec466c9dd0fd2d2b5323a5e76/Lib/enum.py#L205

The solution to 29577 will also fix this.
