 * @assertion Additive expressions invoke the addition operators on objects.
 * additiveExpression:
 *   multiplicativeExpression (additiveOperator multiplicativeExpression)* |
 *   super (additiveOperator multiplicativeExpression)+
 * ;
 * additiveOperator:
 *   '+' |
 *   '-'
 * ;
 * An additive expression is either a multiplicative expression, or an
 * invocation of an additive operator on either super or an expression e1, with
 * argument e2.
 * @description Checks that using an assignment expression as the first operand
 * of an additive expression results in the latter being an operand of the
 * former.
