Well, that was quick. It turns out I was doing some things that violated the Ada95 RM, but my compiler didn't catch them. Thanks, Gene, for informing me of this. Hopefully I don't have anything else with that big a problem. Anyway, the constraints are removed from the iterators. After thinking about it for a while, I like that better, anyway, since it gives the user a little more flexibility.
