  • 38.3.1

    • You can just tell us which expression needs to be evaluated next instead of underlining.
  • 40.3.5
    • There is a slight typo in the book. The extra set of parenthesis around the three (make-CD ...) expressions should be ignored.
  • 40.4.1
• Extra problem:
  • Chapter 34 introduced the functions lookup and add-record. Develop a new version of these functions and use it to write a phone book program without using assignment (or any mutable state). You may tweak the contract if you need to. Can this trick work all the time?
