Honestly I would remove all the dunder variables from the example, they don't add any clarity (and they're not in that file anyway).

No class other than object actually needs to declare __doc__ at all. They just inherit it from object. I think the stubs have it because the stub generator puts it in.

python/mypy#2380 showed a discrepancy between
objectandFunctionTypein stdlib2. The first defined__doc__to bestr, the secondOptional[str]. AsFunctionTypedepends onobject, this is no longer valid.As suggested by @gvanrossum in python/mypy#2380, all
__doc__should be considered Optional.
