    It looks mostly good. I wouldn't use the high bit to differentiate
    the 64-bit operations, though. Since we do not allow to apply it to
    all operations the only effect will be that the compiler has a harder
    time generating the code for the switch statement. If you use
    continuous values a simple jump table can be used and no conditionals.
    Smaller and faster.
