Well that's the whole point, right? We shouldn't conflate the two. I
don't see this as an argument why it would be bad to delete
non-string-keys found in __dict__ from dir()'s return value. I don't
think that the equation

    set(x.__dict__) <= set(dir(x))

provides enough value to try and keep it. A more useful relationship is

    name in dir(x) <==> getattr(x, name) is valid
