> Why not adding both? Properties do have their uses as does __getattr__.

In that case I would just add __getattr__ to module.c, and add a recipe or perhaps a utility module that implements a __getattr__ you can put into your module if you want @property support. That way you can have both but you only need a little bit of code in module.c to check for __getattr__ and call it when you'd otherwise raise AttributeError.
