Given this:

   namespace std
      namespace rdb
         struct float_;

You can have this:

   using namespace std::rdb;

      float_ f;

That is, the names lose the "rdb" part and you're left with "float_," that is spelled almost the same as the built-in type, but that has different behavior. At the least, float_ would include the length/null indicator, but it's behavior will be subtly different from that of float because we can't make UDTs behave completely like built-ins.
