+% Not adding 'encapsulated' as normal word to index; the keyword variant seems sufficient
 A class declared with the keyword \lstinline!encapsulated!\indexinline{encapsulated} (see \lstinline[language=grammar]!class-definition! in the grammar) is called an \firstuse{encapsulated} class.
 By restricting name lookup inside a restricted class in ways defined in this chapter, the meaning of the class is made independent of where it is placed in a package hierarchy.
