Hi all,

I was reading over the list of what's new in Python 2.6 and wondered about this:

> The built-in dir() function now checks for a __dir__() method on the
> objects it receives. This method must return a list of strings containing
> the names of valid attributes for the object, and lets the object control
> the value that dir() produces. Objects that have __getattr__() or
> __getattribute__() methods can use this to advertise pseudo-attributes
> they will honor. (issue 1591665)


Does that sound useful for some of our more dynamic objects?
