| * @assertion Evaluation of an assignment of the form super.v = e proceeds as |
| * follows: |
| * Let g be the method currently executing, and let C be the class in which |
| * g was looked up. Let Sdynamic be the superclass of C. |
| * ... |
| * 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 [o]. |
| * • im.namedArguments evaluates to the value of const {}. |
| * Then the method noSuchMethod() is looked up in Sdynamic 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 this |
| * @description Checks that it is a compile error if there is no setter v= in |
| * class Sdynamic |
