  Do I understand correctly?  You mean An array of no elements, whose
every element is an array of N elements?

  Why is this different from or more useful than any other kind of
array of no elements?

  I am aware that you can get such entities as a result in matrix
operations, but I had always (perhaps mistakenly?)  regarded them as a
degenerate case not useful for further processing, and so didn't feel
that they needed a source syntax.
