This surprised me somewhat, and I must have missed any
discussion/rationale.  Could you elaborate/point me at the relevant
information? 

It seems to me that A.B could be implicit (leaving "module C where"),
from the path. This might help resolve point 3.2[0] Renaming of
Subtrees, since one could add -I (or equivalent options, or modify a
path in an env var) for commonly used directories. 

(Okay, so it would introduce a dependency between the importing source
and the build process.  Is that it?)

[0] ...suggesting a syntax along

	import Org.Com.Microsoft.* as Microsoft.*
	import Microsoft.Foo
	import Microsoft.J++ as Java

giving a shorthand access to deeply nested libraries.
