| * @assertion Evaluation of an assignment of the form e1.v = e2 proceeds as |
| * follows: |
| * The expression e1 is evaluated to an object o1. Then, the expression e2 is |
| * evaluated to an object o2. |
| * ... |
| * It is a dynamic type error if o2 is not null and the interface of the class |
| * of o2 is not a subtype of the actual type of e1.v |
| * @description Checks that it is a dynamic type error if o2 is not null and the |
| * interface of the class of o2 is not a subtype of the actual type of e1.v. |
| * Test the case when e1 is a constant type literal |
