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!

class StaticFileHandler(RequestHandler):
    """A simple handler that can serve static content from a directory.

    To map a path to this handler for a static data directory /var/www,
    you would add a line to your application like:

        application = web.Application([
            (r"/static/(.*)", web.StaticFileHandler, {"path": "/var/www"}),
        ])

This is a barebones GYP file to compile 1 C source file. We are demonstrating that the cflags parameter in gyp files gets completely ignored :(
