This next Tuesday, there will be a combination of lecturing (introducing additional data types and techniques in Lisp) and a fresh optional exercise. However, the programming for this next exercise will be closely related to the kind of implementation we will need for the first obligatory exercise. Hence, as always, please make sure to use your weekly allowance of additional hours for this course (almost nine hours, in addition to our four hours of instruction, each week) to work through the implementation assignment. Happy Valentine!
