The other things that "beginner" tutorials such as this do is they say "lisp" when they really mean "something resembling Scheme". I started a project some time ago to write an elisp interpreter, mostly for fun. But since elisp is much more like Common Lisp than Scheme, it has a surprising amount more syntax than a Scheme does. The parser was much more complex than I initially thought it would be.
