The fact that this works is actually kinda useful for writing 
`opDispatch` wrappers. You can write something like

     auto opDispatch(string name, Args...)(Args args)
     {
         return __traits(getMember, payload, name) = args;
     }

...and it will work for both member functions and member 
variables.
