   I continue to reject the use of "accept" and "reject" here. And I also   
   reject the use of "indicates" wrt to them.   
      
   There's no good reason to suppose this is about grammars and strings   
   rather than propositions about programs. To the extent that they might   
   be isomorphic you need to introduce the notion of grammars and string   
   acceptance by them to give "accept" and "reject" and "indicates" the   
   correct meaning.
