Implement a __dir__ method. This should call the superclass' (e.g.
object's) __dir__ and add whatever it is you want to add to the list.

In general I'd recommend using properties for this kind of thing rather
than messing with __getattr__, __setattr__ and __dir__, especially in
pure Python. I'm no expert on the C API, but I think this should be
possible by setting PyTypeObject.tp_getset
