Uh, what would this xor-multiplication do? If you see "xor" as a
bitwise addition, then the bitwise multiplication is done with the
"and" operator, which all modern CPUs have (and in fact this analogy
is even better than the xor-addition since bitwise multiplication
does not have trouble with carry and therefore never overflows).
