/**
 * @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 that noSuchMethod() is called when getter is declared explicitly
 * ans vg is not a function (doesn't have the method call)
