I wrote elisp.lisp (http://clocc.hg.sourceforge.net/hgweb/clocc/clocc/raw-file/tip/src/cllib/elisp.lisp) years ago to run ELisp code (that uses dynamic bindings) under Common Lisp (that uses lexical bindings). (The gist is to explicitly `declare` all variables `special`). So, at the very least those old emacs lisp programs will still be usable under CL. -- Sam Steingold (http://sds.podval.org/) on darwin Ns 10.3.1894 http://childpsy.net http://calmchildstories.com http://steingoldpsychology.com https://jihadwatch.org https://iris.org.il https://memri.org nobody's life, liberty or property are safe while the legislature is in session
