This is sounds like how I thought it had to work to be effective.  If I 
understand this correctly, the whole modules concept is in fundamental 
conflict with the anything which uses the boost inclusion/dependency 
model - which is every module includes what it uses and nothing else.

In my view the whole modules idea is misconceived.  One more nail in 
coffin of C++ xx standard libraries.

It's time for use to seriously start moving on.
