   > The change seems fine but after the discussion in #13304 I'm not sure I'd advise anyone to use `f() & g()` as there is no way to guarantee short-circuiting and many readers will assume that is what is happening.
   
   Hi @westonpace, I think it is an important ability for this method to *forward reference* for better performance, not only for these rvalue created by the *temporary returned value*, but for more general rvalue in other cases, e.g.
   ```
   Status v = ..., v1 = ...;
   
   use(std::move(v) & v1);
   
   // assume v is no longer used here
   ```
