Assigning to a member of a NULL array has always yielded another NULL
array. While I've never been particularly satisfied with that behavior
either, it has some logical symmetry to it. What do you think the
behavior ought to be? (In particular, if a non-null array should
result, where do we get its dimensions and subscripts from?)
