Common Lisp - A Gentle Introduction to Symbolic Computation
Given I’ve passed through SICP once, quickly grasping common lisp to build stuff and explore the traditional and industrial aspects of lisp (I know clojure exists but traditional…) was my next objective: with decent speed and only solving the somewhat involved exercises, it took me two weeks to complete this book.
The exercises aren’t meant to be a challenge but to adapt to the environment and the topics introduced. The book does not explore concepts with depth (CLOS, macros, etc…) but that shouldn’t be the objective of an introduction anyway.
