That's a contrived example. Perhaps I'm wrong, but I'd assume the 
general use case is that all functions in a module will come from the 
same C++ namespace. For the contrived example above, I think it's fair 
you have to use a contrived solution:

	module s.t;
	extern (C++, S.T):

	int foo();

	struct U {
		static extern (C++, S.T.U):

		int foo();
	}

Alternatively you can use another module for the other namespace.
