Recent changes to slime (quicklisp version) have broken the js-expander Slime Changelog: 2011-03-09 Helmut Eller heller@common-lisp.net
Remove slime-sexp-at-point-for-macroexpansion.
* slime.el (slime-sexp-at-point-for-macroexpansion): Deleted. (slime-eval-macroexpand): Use slime-sexp-at-point instead. (slime-eval-macroexpand-inplace): Use slime-bounds-of-sexp-at-point directly.
I believe this fix should work but my slime fu is weak.
