It would be nice if the module system had more than one error message: 
"Cannot resolve".  I know it is on the list to fix that, but I was 
trying to work on the common and easy cases.

Anyway, you changed the subject to one of implementation detail.  I was 
asking about the spec :-)  Where should I look for specification details 
about the restrictions on duplicate names in the module graph.
