Is there any good reason why C++ namespaces are "closed" in D?

Bindings != wrappers. I agree that wrappers will nearly always 
need to be written, I'm trying to automate the writing of the 
declarations needed to link.

It should be possible to automate translating everything, but 
some things will be tricky in C++. std::vector is quite clearly a 
value type, yet the GNU implementation declares it as a class 
with protected inheritance from _Vector_base. That's going to be 
fun...
