As others have mentioned, all of those are in Common Lisp, either built-in or with with libraries readily available in Quicklisp. Quicklisp didn't exist back then, so it wasn't so easy as it is today, but most of the libraries already existed. Don't get me wrong, I understand the convenience of having all of that built in, minus the crusty parts of Common Lisp, but as far as language features go, I'd say it was evolutionary, not revolutionary.
