In the past, I've wanted something like (null array), which would be consistent since Ada already has (null record).  The language would have to define what the actual bounds of the array are, however, since a program can still refer to A'First or A'Last and they have to be defined to be something.  Starting with Ada 2005, it's now possible to say (1..0 => <>), which makes things better than they were before--at least there's no more problem of having to come up with a dummy value to put on the right side of the arrow.
