I've read about a couple of chapters based on a recommendation that these select couple sections would broaden my view of designing parsers and understanding s-expressions. It did. On the other hand, I skimmed the rest of the book and didn't find anything in particular that I needed out of the text. Thus my choice of 'No and I don't want to' seems like a fair one considering I read way less than 25% of it. Maybe a chapter count poll would be better. Let's call it a 5% for me. I'm guessing that developers don't actually ready cover to cover and cherry pick sections until books reveal more pertinent info later?
