    I would like to encourage KMP to go ahead with a separate proposal for
    ROW-MAJOR-SUBSCRIPTS (or whatever we end up calling it).  Given that, I
    think a version of POSITION that returns a single number for arrays is
    probably the way to go, and users can then turn this into a subscript
    list if they like.  I have a mild aversion to getting a list from some
    function that has heretofore always returned a number or NIL.

In this instance, note that a NIL result could be confused with an
empty list of subscripts, the natural result in the case of a
zero-dimensional array.
