> Since the addition of __dir__, dir(obj) can return arbitrary values. Typically (I guess) this will be used to add dynamically created attributes that this function will fail to find - so it is *more* likely that we will fail to find something in dir than the reverse.
> __dir__ could also be  used to filter non-public members that getattr(...) would find. I would find it odd that getattr finds a member that exists but this function fails. I think this function is more akin to getattr than dir.


> Perhaps a better warning would be that this function may fail to find members that getattr finds?

Ah, yes, and vice versa (well, just yesterday I wrote a descriptor
that always raises AttributeError :-).
