<<Multiplication was just an example of the compilation problem  - division
is the REAL killer - how do you cope with divide-by-zero exceptions in
critical system when all you are allowed is the catch-all exception
handler, (and run-time checks switched off)? Terminating with an exception
is not an option when you are 2 miles above the Atlantic!  I would prefer
to know EXACTLY what is going on in as much of the object code produced
than leave it to the whim of the compiler.

Now wait a moment, that makes no sense at all. All you need to do is:

  begin
     x := y / z;
  exception
     when Constraint_Error =>
       ... anythingf you please
  end;

Furthermore, if you do want to override division, you can always do

    x := Divide (y, z);

So while I agree this is annoying, the implication that it is other than
a minor annoyance is overblown!
