+1 here too. This could be added easily to Python 2.6.

+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.
