/**
 * @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 vo is an instance of Type
 * but o is not a constant type literal, then if g is a getter that forwards
 * to a static getter, getter lookup fails. 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 symbol 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 vo and invoked with argument
 * im, and the result of this invocation is the result of evaluating i.
 * @description Checks that the value of method invocation is the value
 * returned by function vg.
