Title: The book is a mess, errors everywhere, hard to understand
Review: I have no doubt that the author knows compilers, but the reader of this book will not gain much from it. The code samples are bug-riddled, the text has obvious errors, typos everywhere, sections mislabeled, and generally it just looks like it was a crazy sloppy job. Maybe it had to get to the publisher in time to make the students in his course buy the book? It does say "preliminary edition" but this is little better than a first draft.
