+Note that \c{?:} (ternary operator) and \c{!} (logical not) are
+right-associative. Unlike C++, all the comparison operators have the same
+precedence. A qualified name cannot be combined with any other operator
+(including ternary) unless enclosed in parentheses. The \c{eval} option
+in the \c{eval-value} production shall contain single value only (no
+commas).
