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”.
Oh wait, it really ships with a GUI-based IDE… I’m convinced—Allegro is good, especially when paid. When talking about free version, my non-introspection comments still apply, but they are kind of implied for a free version of proprietary product.
