Hi Erik, I've had an opportunity to return to Babel support for common lisp recently. I just copied over the existing ob-clojure.el file to ob-lisp.el and changed the clojure/swank specific parts. The resulting file seems to work after some initial tests and is exceedingly simple. If this works for you as well, then I'd propose replacing the existing ob-lisp.el with this new implementation. Please let me know what you think. Thanks -- Eric
