    I didn't see any problems in there. I just thought
    if a code has such a restriction, generally it is better
    to have an explicit assertion in the code also
    not only in comments. Since those functions are
    EXPORTed ones I thought there will be a possibility
    of misusing them, although they could be found
    quickly without this facility. :-)
