/**
 * @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
