Why is that a problem? As I pointed out, he's just showed us a metaprogramming trick he thought was cool. That is no indication that he is an inept programmer or someone that should be allowed to teach something like RubyMotion (if he was writing a book on metaprogramming, that's another thing).

No problem at all, I was talking about the book. Even if he hasn't lied, when one reads the "author" section, it sounds like he's an expert. In the description of the book it also says it can help you even if you are a "veteran", which might be true (or not), but makes one think he is a veteran too. It's misleading.
