Couldn't C++ anonymous namespaces solve this?

e.g.

   #include <string>

   namespace {
     using namespace std;

     namespace my_wacky_namespace {
       string my_crazy_fun ();
     }
   }

   using namespace my_wacky_namespace;

   int string = 3;

   std::string test ()
   {
     return my_crazy_fun ();
   }

... compiles fine.

[I'm not entirely sure I really understand how anonymous namespaces
work, but they seem to do the right thing here ...]
