+The postfix array index and postfix access operators are not merely expression operators in the normal sense that \lstinline!a.b[1]! can be treated as \lstinline!a.(b[1])!.
 Instead, these operators need to be considered jointly to identify an entire \lstinline[language=grammar]!component-reference! (one of the alternative productions for \lstinline[language=grammar]!primary! in the grammar) which is the smallest unit that can be seen as an expression in itself.
-Postfix array index and postifx access can only be applied immediately to a \lstinline[language=grammar]!component-reference!; not even parentheses around the left operand are allowed.

 The relation between \lstinline!a.x!, \lstinline!a.x[2]!, and \lstinline!(a.x)[2]! illustrates the effect of giving higher precedence to array index than postfix access.
 Had the precedence been equal, this would have changed the meaning of \lstinline!a.x[2]! to the same thing that \lstinline!(a.x)[2]! expresses, being a component reference of type \lstinline!Real[2]!.
-Note that \lstinline!(a.x)[2]! was illegal in version 3.6 and earlier.
