In the interrest of KISS, I'd leave the emptiness concept out of the
picture.  Unlike isset-ness, an emptiness coalesce *can* be done in
userspace:

function firstNotEmpty() {
    $vars = func_get_args();
    foreach($vars as $var)
        if (!empty($var)) return $var;
    return NULL;
}

There's enough....contention over the undeniably useful and
not-implementable-in-userspace parts of this thread that it's not worth
muddling it up with things that are a simple matter to do in userspace.  It
doesn't matter that notempty() and ifsetor() could easily be implemented by
the same opcode (just like isset/empty are).
