-The postfix array index and postfix access operators can both be part of a \lstinline[language=grammar]!component-reference! (one of the alternative productions for \lstinline[language=grammar]!primary! in the grammar) and be applied to general expressions when the left operand is parenthesized.
-Directly using both postfix access operator and postfix array index in a \lstinline[language=grammar]!component-reference! has a special intuitive meaning.
