Wow. I was already impressed with the book, but after reading about what was happening behind the scenes, I'm truly in awe. I especially appreciate the work you put into making sure that the code snippets are accurate to the actual source code. Far too many books omit crucial steps or contain faulty code. I also found it really heartening how you kept working through the tough times. We're all going through some challenging times right now and I have found that working on my projects (including a compiler!) has given me a small bit of satisfaction.
