  * Accept unqualified method declarations in the body of an instance
  of a qualified class.  The methods are unambiguously those of the
  qualified class and do not require explicit qualification.  (Indeed,
  in strict H'98 it is no longer possible to qualify them, but nhc98
  still permits them to be qualified, in which case of course the
  qualification must match.)
