For example:

for I in A'Range loop
   Sum := Sum + A (I) + B (I - A'First + B'First);
end loop;

without order changing one cannot factor out the loop constant
(B'First - A'First). Should the programmer take care of that?

As a programmer I like to hand that stuff over to you, a compiler
designer. In case, I will always have an abilitity to blame that
"stupid compiler"! (:-))
