I agree and what about:

C : Integer;
A : Boolean;

if A = True then
  A = C = 1;
end if;

Of course, the current implementation is quite clear:

if A = True then
  A := C = 1;
end if;

I really think that this whole thread serve to nothing. Russ, the best way to
have your proposal intregrated at some point is to propose it to the
ARG. Maybe they will understand better than us the added value!

Pascal.
