  19. class X {
  20. #ifdef X_FRIENDS

  27. The above hack should let you develop a tightly-coupled hierarchy with
  28. minimal fuss until closure can be applied and the final friend declaration
  29. inserted in its place.
  30.  
  31. In my opinion a tightly-coupled framework must be finite a-priori.  I can't
  32. reconcile this requirement with that of inherited friendship.
