 I believe the code given is substantially wrong.   Consider, however, the 
 following testcase:
 ---
 template< typename X, typename Y, int = 1 >
  struct C1 {
   template< int, int >
    struct C2 {
      enum { v = 0 };
    };
 };
 
 enum Xx { a, b, c, d };
 
 template <> template <>
  struct C1< Xx, Xx >::C2< a, a > {
    enum { v = 1 };
  };
 
 template< typename X >
  struct D: public C1< X, X, 5 > {
   template< int, int > struct C2 {
      enum { v = 2 };
    };
 
 #include <iostream>
  int main() {
    std::cout << D< Xx >::C2< a, a >::v << std::endl;
 // And the next case...
    std::cout << C1< Xx, Xx >::C2< a, a >::v << std::endl;
  }
 ---
 
 This compiles perfectly and gives correct results.
 
 So I'm guessing this can be closed...
 
 Do I need to add a testcase for this, or are there enough already?
