 * @assertion If getter lookup has also failed, then a new instance im of the
 * predefined class Invocation is created, such that :
 * - im.isMethod evaluates to true.
 * - im.memberName evaluates to ’m’.
 * - im.positionalArguments evaluates to an immutable list with the same values
 * as [o1, ..., on].
 * - im.namedArguments evaluates to an immutable map with the same keys
 * and values as {xn+1:on+1, ..., xn+k:on+k}.
 * Then the method noSuchMethod() is looked up in S and invoked on this with
 * argument im, and the result of this invocation is the result of evaluating i.
 * @description Checks the result of invocation if the method noSuchMethod() invoked.
