struct nil{};

template<T, Rest=nil>
class A : public Rest {
public:
      void foo( T );
      using Rest::foo;
};

Let say we have instantiation A<int,A<float,A<char> > >. Without using, void 
foo( int ) will hide all other overloads. I could add foo to nil. But I do 
not think it's an issue here.
