This is not a bug, it's called name hiding.



For d.to() the compiler does name lookup for  "to" in the scope of derived and

finds a name, so it stops looking. Then overload resolution tries to match the

arguments to the function and fails.



You need to re-declare the names in the derived class so all overloaded names

are visible in the derived class.



  using base::to;

  using base::from;
