Should an 'extern(C++, "ns"):' override previous ones in the same scope?

The original extern(C++) worked the same way. Since it was 
implemented in v2.066.0 by the looks of it. IIRC the only thing 
the PR did was basically remove the code that added new objects. 
So it's to be expected they behave the same way.

     extern(C++, ns1):
     extern(C++, ns2):
     void foo();

     pragma(msg, foo.mangleof);

     void main() { }

Since      2.066.0: Success with output: _ZN3ns13ns23fooEv
