What triggered me to post it was that I saw in comp.std.c++ a
strange "Proposal: Compilation-unit scoped private member functions"
that received some positive feedback, so may be there is some
market for idiom like that? Idiom (sorry, I do not have name):

<nod>, yes I have used something similar to this as well. This idiom is
also useful when you have the need that a tester needs to have access to
class internals without exposing the test framework in the class
declaration. My own variation of this idiom is to replace the nested
class by a friend declaration, but the effects are similar.

namespace n {
  // A.hpp
  class A
  {
  public:
      // public interface
      int PublicGetter() const;
      int PublicSetter(int param);
  private:
      friend class P;
      int data;
  };
}
