| * @assertion If the method lookup has failed, then let g be the result of |
| * looking up getter m in vo with respect to L. |
| * If the getter lookup succeeded, let vg be the value of the getter invocation o.m. |
| * Then the value of i is the result of invoking the static method Function.apply() |
| * with arguments v.g, [o1, ..., on], {xn+1:on+1, ..., xn+k:on+k }. |
| * 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 o and invoked with argument im, |
| * and the result of this invocation is the result of evaluating i. |
| * @description Checks the result of invocation if the method and getter lookup has failed. |
