I'm the author. In fact, the first bit of advice I have in the book is: Don't. DSLs often involve metaprogramming, but they don't have to. I'm writing it to record the code practices that I have found useful in getting things right and gather advice and tips from others who have done the same. DSLs are always about communication, so my goal is to create a book that helps developers communicate the purpose of the aspects of their project through code.
