Well, as an author of the Hierarchical Modules addendum, and as a
compiler maintainer, I am already reasonably convinced of the utility
of this suggestion.  It does significantly alter the semantics
of import/export, in a way that the original Hierarchical Modules
addendum does not, but as Iavor pointed out, this is not necessarily
a bad thing.

What we now need is a precise definition.  After that, contributions
of code to implement it would also be welcome.  :-)
