| * @assertion Evaluation of an assignment of the form e1.v = e2 proceeds as |
| * follows: |
| * ... |
| * If the setter lookup has failed, then a new instance im of the predefined |
| * class Invocation is created, such that : |
| * • im.isSetter evaluates to true. |
| * • im.memberName evaluates to the symbol v=. |
| * • im.positionalArguments evaluates to an immutable list with the same values |
| * as [o2]. |
| * • im.namedArguments evaluates to the value of const {}. |
| * Then the method noSuchMethod() is looked up in o1 and invoked with |
| * argument im. However, if the implementation found cannot be invoked with |
| * a single positional argument, the implementation of noSuchMethod() in class |
| * Object is invoked on o1 |
| * @description Checks that if class has no noSuchMethod then the |
| * implementation of noSuchMethod() in class Object is invoked and this produces |
| * NoSuchMethodError |
