One question, though, on the tail-recursive feature. It's nice to have but is it really, really important? Elisp isn't (right?), and we've been doing fine without proper tail recursion. Also, is CLISP tail-recursive? That fact that ANSI CL doesn't require it doesn't mean we can't have it. I don't have great preferences to either Scheme or CL. I think it would be great to replace elisp with one of these. Ray
