I’ve been doing much messing about with Common Lisp lately and have had a hiccup or two regarding the Common Lisp Object System (CLOS). I’ve gone back and re-read the “object reorientation” chapters from PCL (which you should buy) but have gotten confused. This is nothing against PCL as it is a wonderful book but what can I say? I’m used to object-orientation looking more like the Python/Ruby/Smalltalk (classes) or JavaScript (prototypes). So, I went digging about and found two links which I’ll be trying out. - Fundamentals of CLOS - A brief guide to CLOS - Warp speed introduction to CLOS

(suggested by xach)

If there are any other good ones, let me know and I’ll add them.
