Truly one of the best books in our field; very well done.

Doing the tree-walk interpreter (the first “half” of the book) took two weekends, working much of the day on Saturdays and Sundays.

When I went through it, I built my interpreter in another language, and added other features as I went along. Both helped solidify the concepts. I often had to pull out my additional features as I learned better in subsequent chapters; getting to see the difference between my amateur approach versus the author’s experienced methods was quite helpful!
