 * @assertion If the method lookup has failed, then let g be the result of
 * looking up getter m in Sdynamic with respect to L. If the getter lookup
 * succeeded, let vg be the value of the getter invocation super.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}.
 * @description Checks that the result of super method invocation is the result
 * of calling Function.apply on v.g, [o1, ..., on], {xn+1:on+1, ..., xn+k:on+k}
