I agree 100% here, and the solution was described at least in two
articles before or during the Ada 9X effort. I still don't understand
why it's not in the language.
Moreover, most compilers I have used do a very good job of putting
packages in a 'good' elaboration order, to the point that I almost never
bother using the elaboration pragmas, taking the risk of hitting a bad
compiler some time in the future (which won't be GNAT, given the effort
being made to solve the problem :-).
I really think this elaboration stuff should fixed in an AI (of course
only the part that ensures Program_Error is not raised on a subprogram
call or generic instantiation). Do you think that would be possible, or
will we have to wait until Ada 0X ? :-)
