But what about the guys who have written their own private `foo'-package ? Force a recompile and have them fix their surprisingly-now-buggy code which has been legal elisp for years ?

Hrvoje> Why do you call non-sense anything that is not strictly ANSI Hrvoje> conformant? If you could tell me where the sense is of using some language (or even worse: an implementation) not standarized when standarized versions exist ... ? But I didn't meant to be rude, I apologize for being too offensive. Hrvoje> Yeah, and Java and C++. Why not add SNOBOL, for good Hrvoje> measure? Haha. I was just thinking of the re-occuring threads in comp.emacs.* but certainly won't want that for myself. But if the engine would be able to support language X, and there is somebody who wants to implement and use X, hey, who am I stopping him from doing so ? Hrvoje> I did, but you weren't listening. Nope, you were not. Do you want to replace Emacs Lisp with (a substrate of a) Common Lisp (_implementation_) or do you want to two concurrent lisp engines ? AFAIU, you want the former, but I'm by no means sure. [CMUCL] Hrvoje> 17f coredumped on me even on trivial examples. :-( I haven't read comp.lang.lisp for a while, and I haven't seen anybody reporting problems (which of course doesn't mean that they don't exist).
