Arithmetic operations are + - * / and mod (or rem). :)
OK, i see the difference: logxor of two fixnums is fixnum, and you can
do optimizations in frames of standard; but it doesn't hold for
arithmetics. That's is why I ask create distinct (non-standard)
functions.

Perl is a language where 2 x 2 is not equal to 4.
