Enum has no attribute "__members__"

[gopar]

Mypy spits out error: "SomeEnum" has no attribute "__members__" with the following code:

from enum import Enum

class SomeEnum(Enum):
    ONE = 1
    TWO = 2

SomeEnum.__members__

__members__ exists and is documented in the py docs

Mypy version: 0.501
Python: 3.6.0

I think this is being tracked in python/typeshed#854.

Indeed. I should pick up my work on Enum.
