    This is interesting. I’ve personally contributed implementations of two of the CDR’s to Quicklisp - EQUALS and having generic hash tables.

    I’ve seen in the last few years several ‘Next Generation Common Lisp’ systems. This one might be better? Hard to say. At least it doesn’t have the conceit of dropping plain Common Lisp, I think. Interoperability is a terribly useful property. In particular, when I write Common Lisp, I have the comfort of knowing I won’t have to rewrite it because the language changed under me.
