I love it too, but I think he author(s) want much more than teach a language. They want to teach designing programs (in arbitrary language I think). They have chosen student languages (subsets of racket) to talk about design.
To Matthias: I love the book very much as said above. Nevertheless I have some problems how the N-queens problem is presented. I already wrote you abuot this a long time ago. In my opinion: first think about the essentials of the problem (in natural language, possibly applying some mathematics) Then you come up with a very much simpler representation of data and consequently simpler ways for a solution (or all solutions). If only one solution is desired, the student should be directed to: https://en.wikipedia.org/wiki/Eight_queens_puzzle. Using the algorithm presented in this web-page, a 1000000 x 1000000 solution is found within seconds and within reasonably limited memory. MHO. Nevertheless, proficiat with the new edition!
