Thanks for posting all these! I think you're the only person in the entire internet who has both a) devoted time to solving the problem, and b) blogged about it!
For me, I agree that #9 has caused the most significant restructuring of object responsibilities. Unfortunately rule #9, combined with Rule #3 (wrap all primitives and strings), and Rule #2 (Don't use the ELSE keyword), has left me at an ugly crossroads.
I'm getting the idea that squeezing the last bits of object calisthenics compliance out of a solution is just not worth it. For me, I'm down to exactly two rule violations, and "fixing" either will require bending the rules. So, for inspiration I'm looking around at what everyone else is saying about object calisthenics...and your series of blog posts is about all I can find on the subject.
