4 A typedef-name that names a class is a class-name (_class.name_).   If
  a  typedef-name is used 
  1) following the class-key in an elaborated-type-specifier 
  2) or in the class-head of a class declaration 
  3) or is used as the identifier in the declarator for a
  constructor or destructor  declaration 
  the program is ill-formed.  [Example:
