OK, that makes sense (assuming that the product of no values is 1, which
I suppose is reasonable). Note, however, that the SRFI 47 constructors
do not permit the creation of rank-0 arrays, and it even uses rank 0 to
indicate that an object isn't an array at all, so I don't mind if you
can't create them with the literal syntax either.
