MULF and DIVF could be useful (but note that many people spell the first
as MULTF).  However, I don't think that MUL(T)F and DIVF should take a
default factor/divisor argument --- personally, I would find (DIVF FORM)
somewhat confusing.

I don't really see the value of aliases for PLUSP and MINUSP, and I have
some doubts about NON-ZERO-P too.

Best,
