A system is always be faster when reimplemented from scratch.
I redid the kernel of our expert system shell in pure CLOS and asked a
student to port the same stuff to c++.
My reimplementation gave a factor of 10 speed improvement to the original
lisp version (and it does not cons at all) while to my surprise the c++
code is not faster than my clos code (MCL versus CodeWarrior 6 on Mac with
sys 7.5.1)
