| * @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 an additive expression of the form
|
| * multiplicativeExpression ('+' multiplicativeExpression)*
|
| * must have at least two operands.
|
| * Note that there is no unary plus operator in dart.
