Arrays with zero dimensions.

Is it really of cosmic importance that we allow dimensions of zero?
We sure could invent a lot of baggage to handle it correctly, but...
We already have it:
(array-dimensions "") => (0)
The problems presented so far only come up when the number of dimensions
is 2 or more. My answer to that is that such arrays have legitimate
structure and are therefore meaningful. Zero-dimensional arrays
likewise have legitimate structure, which is why I assume they were
included in the language.
