The *serious* problem is that the added scope does not appear to add 
practical value, yet has a non-zero cost.  And yes I've seen your 
example with two same-named symbols in the same module, but I really 
don't understand why *that* is a serious problem that the namespace 
scope is worth introducing to solve.

And I am not personally arguing for D modules mapping to C++ namespaces 
- the alternative feature I have in mind is extern(C++, "namespace") 
affecting mangling and *nothing else*.
