Hi there, I use ILISP for Common Lisp, but not for Scheme. I assumed, (setq lisp-source-modes '(lisp-mode)) would prevent ILISP from messing with scheme-mode. Unfortunately, it doesn't prevent ILISP from changing the scheme-mode keymap. I submit that's wrong. Here's a patch. (Please cc me on any followups, as I'm not subscribed to ilisp-devel@.)
