I read the seven messages in this discussion about multidimensional arrays where
some of the dimensions (other than the last) are zero. My opinion is that the
language semantics are correct and consistent, and the problem lies solely in
the print syntax. The best suggestion so far, in my opinion, is the one from
Mlynarik that when array cannot be meaningfully be printed with #A it should
be printed with #.(MAKE-ARRAY ...).
