Does this suffice?

        fn prompt {
                if (!~ $apid $lastapid) {
                        echo kill $apid
                        lastapid=$apid
                }
        }

I didn't really give much thought to this; just left the "bug" in the
man page.  But doesn't this function come close?  You can use `myshift
x' to shift $x by one, or `myshift y 3' to shift $y by 3.  The only flaw
is that `myshift a' doesn't work.

    fn myshift { a=$*; *=$$a(1); shift $a(2); $a(1)=$* }
