> get readers to understand there’s no magic in there and nothing keeping them out This was a key feature of the book for me; reading it really helped me grok that compilers/interpreters are just programs. Very complicated programs, perhaps, but still many of the same concerns that apply to my day job writing applications. It's code all the way down, and that feels like a hugely useful insight to have. Plus I think I now have the language bug myself. :) Well done, Bob, and congratulations! Can't wait to be able to buy a copy.
