Re: [sv-bc] Extern modules question

I think (hope?) that the intention of this was really that
extern modules have normal lexical visibility.  I doubt that
the intent of the "only within the level of hierarchy in which
they were declared" phrase was to limit *lexical* visibility;
I expect that the intent there was to limit *hierarchical*
visibility.

So my answer to your question would be that a $unit extern
module declaration would be visible throughout the compilation
unit following normal lexical resolution (like a type).
