When calling the following code, I expected the call to myJSObject inside
testJSOCall to pass the current
scope as a ScriptObjectMirror to JSObjectImpl's call method as the thiz
argument. In this case without
modifying the call to myJSObject() should 'this' automatically be passed to
the call() method?

Thanks,
