Yeah, but if they had decided to specify the order instead of leaving it implementation-defined, what order could they have chosen? Alphabetical? (Think about what joy that would have caused the ARG when Unicode support was added to the language!!!) I think the problem is that, unlike some cases (like subprogram parameters, where the language designers *could* have specified left-to-right evaluation instead of implementation-defined order), there's no natural ordering of library packages in a program. So I don't even see the beginning of a solution.
