Personaly i found abcl a bad experience.
Thoughts on ecl & clisp ?
sbcl works nice & fine. But i’t’s the only lisp implementation i know.
There are good books on racket-scheme & chez-cheme.
The only book i know for lisp is, “Common lisp , a gentle introduction to symbolic computing”.
My pet peeve: People never looking at the sidebar of this very subreddit.
Aah , i see to the right. But aren’t the books “OLD ?”
CL is, like, fourty? years old now. These books describe the standardized language, so most of their gotchas apply to any conforming implementation. So yes, the books are “OLD”, and yes, they are “GOOD”.
Welcome to Reddit :-). That is the common theme of all subreddits I am afraid.
