change v8 typeof oporator to return 'object' instead of 'function' on host objects.

Is there a way to change typeof [HostObject] to return 'object' instead of 'function' .

        public class TestClass
        {
            public string Name { get; set; }
        }

        [TestMethod, TestCategory("V8ScriptEngine")]
        public void V8_typeof()
        {
            var testClass = new TestClass() { Name = "lisa" };
            engine.AddHostObject("testClass", testClass);
            Assert.AreEqual("object", (string)engine.Evaluate("typeof testClass"));
        }

Hi @dirkelfman,

Unfortunately V8's typeof implementation returns "function" for all objects that are callable, which currently includes all host objects. We've discussed this with the V8 team here.

Many host objects are indeed callable, or potentially callable (delegates, host types, dynamic objects, "tear-off" methods, etc.), and will therefore always return "function". It might be possible to discern non-callable host objects and instantiate them through a dedicated non-callable template. We'll take a look.

Thanks!

In Version 5.5.3, only delegates (and a few other special kinds of host objects) return "function" for typeof. The operator returns "object" for all other host objects.
