Lisp interpreter in 90 lines of C++

I've enjoyed reading Peter Norvig's recent articles on Lisp. He implements a Scheme interpreter in 90 lines of Python in the first, and develops it further in the second.

Just for fun I wondered if I could write one in C++. My goals would be

1. A Lisp interpreter that would complete Peter's Lis.py test cases correctly...
2. ...in no more than 90 lines of C++.

Although I've been thinking about this for a few weeks, as I write this I have not written a line of the code. I'm pretty sure I will achieve 1, and 2 will be... a piece of cake!

Continued from Results from the January 2012 Core Skills Course, by Gregory Brown

For our integration exercise we had students build multi-user email based applications. All ten students who completed the course worked on this exercise, and we ended up with everything from an email-based wiki to a system for sharing funny stories and jokes.

For our academic exercise, we asked students to make use of Markov Chains to do something interested. Seven of our students participated in this exercise, and we ended up all sorts of cool results, including a jazz chart generator and a tool which predicts movements in currency exchange rates.
