Exactly which part confuses you?

Yes, that is correct.

| the standard ? 

What I meant is this:

  struct X {
      int C;

      template<class> void func(); 
  }; 


  template<class C>
    void X::func()
    {
       C c;     // ERROR: C is not a type.
    }

In the definition of X::func(), lookup for C will find X::C instead of
the template parameter.  In the example you gave, X::C is a
non-template, so it will cause an error -- because the function gets
rewritten out of the class definition..
