While this is certainly more explicit, it also means that every time
you create or rename a shared routine, you have to declare and at least
two places. Perhaps being explicit is it's own reward. I know I've found
that maintaining export/import interfaces between highly related modules
to be cumbersome at times.
I can't see I have a better pattern to suggest for this case, rather
it's a question I've run into myself and haven't fully resolved.
