   To override the Ada mandate and deliberately adopt C++ on a real

   constitutes criminal negligence.

Jim, I suggest you relax a bit.

As to the fourth claim of yours, you could try getting in touch with
Bjarne Stroustrup and ask him about places it's being used.  Last time
I heard, central telephone switching gear (the size of 5ESS) is coded
in C++.  After all, this _is_ AT&T...  These animals implement CCITT
Signalling System number 7.  The specs are 1500 (A-sized) pages of
gory details and 500 pages of verification and validation suites.  I
posted the table of contents of SS7 to comp.std.internat some time
ago.

Telephone exchanges are "hard realtime, life-critical, very big, very
complex" to check off your list.

I'm not particularly interested in arguing with you, so this is only
for the benefit of those who would otherwise tend to believe you.
