Its a part of Chapter 17, just so you know its only a small exercise showing the beauty of Clojure, Lisp and Macros. Its only about 6 six pages. The footnote:
The code in this section is based on *debug-repl* created by the amazing George Jahad, extended by Alex Osborne, and integrated into Swank-Clojure by Hugo Duncan. So maybe check those out. That said I think its a really good book and Manning often has specials going so you get Joy of Clojure 1 & 2 for cheap.
