This is such a great post, and if you are new to Lisp or Compilers or PLT I would recommend investing time in it. > I think it meets Alan Kay's 1972 claim that you could define the "most powerful language in the world" in "a page of code." (However, I think Alan would disagree, because he would count the Python compiler as part of the code, putting me well over a page.) If anyone is curious, I have some ideas on how you could more precisely define this problem and an objective mathematical way of evaluating it. Shoot me an email if curious.
