I would like to call attention to the SF bugs
[ 1891216 ] is(if a>0 and a>0 and a>0 ...) => internal error
[ 1891911 ] is(f(a+b+c)) --> Lisp error
[ 1726550 ] not bugs
I think these bugs are related--fix one bug and you'll get two bonus
points! And they make it impossible for me to test some interesting
(well, at least I think) experimental linearalgebra code. As a
mathematician who has been known to program, the bugs in db.lisp and
friends are beyond me.
