I think that maybe I could have stated my point more clearly. I was just pointing out that except for a few examples, RBP does not talk much about Rails at all. I can say with near certainty, however, that the dynamic toolkit chapter will really help folks understand how Rails implements domain languages and does its meta-programming magic. What my book won't tell you is anything about Rails's API.
