I confess I'm not quite sure what the right answer is here. It would seem
overkill to have both `I` and something that's the same thing, except sized.
OTOH, I see the attraction.
Maybe if it were part of a general mechanism, e.g., SizedArrayOperator{O,N}
(for performing an operation `O` on array with `N` dimensions of specified
size) it wouldn't be so bad. That would rely on finding other uses for this
concept, however.
