Just published the second edition of "LISP From Nothing" with a new chapter on Lambda Calculus that sheds light on the question if LAMBDA is enough to implement LISP. Also contains other minor additions and corrections. See the homepage for details.

#LISP

Back cover of the books "LISP From Nothing". Blurb:
* What is the minimal LISP language that can interpret itself?
* What is the smallest LISP that can compile itself?
* What was LISP hacking like in the age of punch cards, teletypes, and mainframe computers?
* How is LISP related to Lambda Calculus?
This text plays with the theme of minimal LISP by providing several implementations from a simple metacircular evaluator to a full compiler that emits a single, self-contained C program. The discussion is embedded in reflections on what hacking looked like in the early days of LISP.
