Sorry to reiterate the previous post but is that really the case?

   void FuncTemplate(...)(...) {
     X.FreeFunc(Y);
   }

   import ModuleA; // contains FreeFunc
   import ModuleB; // contains a conflicting FreeFunc overload

   FuncTemplate!()(); // fails

Where is the difference with writing generic code with operators 
(overloaded or not)?
