    The notion is that they are *some* kind of description on how the system
    call has been augmented. The bitwidths and argument numbers are
    non-overlapping and visually very different, so are not subject to
    confusion. Your argument makes about as much sense as saying the letter
    "a" should have the same meaning in every context.
