Hi, Submitter here,

I stumble upon that article from my bookmarks while pouring my latest side project (http://www.learn-computing-directory.org/languages-and-progr...) and thought about submitting it to HN. By the way, feel free to give me feedbacks about the directory! (in still in very alpha state but already online). I only fill for the moment the "Algorithms and Data Structures", "Compilers" and "Theory of computation" topics.

Two great articles that complements perfectly the one submitted are LISP interpreters in Python from Norvig: http://norvig.com/lispy.html and http://norvig.com/lispy2.html Also, the book "Understanding Computation" (http://computationbook.com/) can be a great companion as there is a section about Lambda Calculus.

Jérémie.
