(- 3) ==> -3 was a feature that wasn't retrofitted to DIFFERENCE.
So who will offer their neck in sacrifice to bring DIFFERENCE and
QUOTIENT into line? While we're at it, we might as well mention the
lack of consistent ordering of the floating point operations in
(+ A B C) and (- A B C): compiled code performs the operations
left-to-right, whereas the interpreter does it right-to-left. All
would be fine except for the non-associativity of floating-point.
Has anyone actually been bugged by this difference? (and who else
has been bugged by this DIFFERENCE?)
