Finally an answer to my original question. It is interesting how we can bounce around all over the place in response to a simple question, dispensing advice, proclaiming our preferences, and ranting our doctrine before someone comes forward with exactly the information we were seeking. Thank you Vernon. I can now announce to my students that 7e7 will indeed be programmed largely in Ada. In fact, I am giving a briefing to a group of engineers next Friday on the subject of software practice in safety-critical environments, and this will be useful information. I also intend to introduce them to the ideas in SPARK along with other good stuff. Naturally, my briefing will not be biased toward Ada.
