+1 here, too.
It would also allow objects which override __getattribute__ and/or __getattr__
to make dir() provide a sane answer (or raise an exception to indicate that a
sane answer isn't possible). (This was something that actually came up when
trying to implement a namespace object that *didn't* automatically fall back
to its class namespace for Python level attribute access)
For backwards compatibility, dir() could still fall back to the current
mechanism if __dir__ isn't found.
Cheers,
Nick.
