I’m surprised he hadn’t added “Land of Lisp”.
Yeah, LoL was an interesting experience. I could write shorter Python versions of most of the lisp code in the book, but it was an enjoyable introduction.
I remember going through the first 6 chapters and often going on the CommonLisp channel on free node to ask questions and eventually found out it was either wrong or misleading in many of the fundamentals. I tried to keep going through it but eventually gave up and picked the much better practical common lisp.
