interactive scripts?
I use clisp for all scripting, interactive and not.
Common Lisp is more powerful than Emacs Lisp and clisp is faster than
emacs.

I have been experimenting with clisp. But I think that Emacs Lisp does a
pretty good job. I translated a script I wrote in Emacs Lisp to CL. The
Emacs Lisp version needed 51 seconds on a certain data set. When using
clisp with the converted code, clisp needs 79 seconds. That is more as
50% longer.


did you compile the CL code?
if it is a script, you might want to add "-C" to the "#!/.../clisp" line to enable on-the-fly compilation.
