I know this is a curmudgeonly thing to say, but I'm happy to see one of these "implementing Lisp" articles where someone started with a lower-level language than Lisp. It just seems like you miss out on a lot of interesting learning if you start with something like Ruby or Python that is so close to Lisp already. For example, implementing lambda with a Python lambda...really? You are missing a giant a-ha moment there, as you can see from this article. Note: implementing a metacircular interpreter for Lisp in Lisp is a beautiful special case exception to my curmudgeonliness.
