The sample implementation of specialized arrays by default does no
checking of indices and assumes that every multi-index passed to a
getter or setter is valid.

Up till now trying to make an empty interval raised an exception, as it
seemed that, in general, making an array with no elements wasn't very
useful.  So at least some indices into the array are valid.

Do you expect that accessing or storing something into an array with
empty domain will always throw an exception?
