Common Lisp Is Not a Single Language, It Is Lots
Lisp is an ambiguous category. But Common Lisp isn't, right? It's a restricted self-sufficient language, after all.
So CLtL2 (as both the book and the language), although including CLOS and other niceties discussed below... Is not object-oriented at its initial core. All these classes add type checking and convenient slot access with e.g. with-slots. So Clojure feels (after programming some sufficiently big projects in it)... Lispy (sorry for the linguistic abuse here).
