Because that might be ill-defined, I guess.
A more interesting question is why Empty'First does not raise any
exception. After all, there is no any lower bound of an empty index range.
Provided, that empty arrays are all same, of course. If not, then another
interesting question would appear: how to make an empty array with the
lower bound Integer'First?
