Sean I agree that TDD would really make sure that we can script such object. I do not know how to motivate people to do so. In bloc I started to write tests and I immediately found bugs. So it was positive and may be we should have a group of people writing tests. Now I have to finish the mooc and I was waiting that bloc stabilise again.Because I spent time writing comments and they are probably wrong now especially since
writing comments on thing you do not master is a PAIN.
