[Voted into the WP at the November, 2010 meeting as part of paperN3206.]
The meaning of the[[base_check]] and[[hiding]] attributes is defined in terms of hiding asdescribed in _N4868_.6.4.10 [basic.scope.hiding]. In that section,however, hiding is orthogonal to overriding: practically bydefinition, a function that overrides a base class virtualfunction also hides it. According to the current specification,the[[override]] and[[hiding]] attributeswould always need to be specified together on every overridingfunction in a[[base_check]] class. This is presumablyunintended, so the current wording should be amended so that[[override]] implies[[hiding]] or somesuch.
