All we're asking for is that C++ namespaces do **nothing**

If I do that, the next bug report will be:
extern (C++, "ab") { void foo(); }
extern (C++, "cd") { void foo(); } // Error, foo() is already
declared
foo(); // which one gets called?
The reason namespaces were added to C++ is to not have such
name collisions. Namespaces in C++ introduce a scope. D cannot
interoperate with this without introducing a scope as well.
Wouldn't something like this would prevent that :
extern (C++, "ab") { void foo(); }
extern (C++, "cd", "s") { void foo(); } // s is an optional D
scope
foo(); // works
s.foo(); // works too
Of course, it will imply some syntax change on the extern
keyword, as a new optional parameter will be added.
