[Voted into the WP at the November, 2010 meeting in paper N3206.]

Notes from the August, 2010 meeting:

CWG expressed a preference for non-contextual keywords for these features.

The facility for checking hiding and overriding of base class members should not use the attribute syntax but should use keywords instead. Concerns about breaking code by changing current identifiers into keywords can be addressed by using contextual keywords, i.e., by putting the keywords into syntactic locations where identifiers cannot appear and thus continuing to allow their use as ordinary identifiers in other contexts.
