QJSEngine::evaluate documentation example contains a failure

The example in the documentation uses two arguments for call while only one is permitted
QJSValue fun = myEngine.evaluate("(function(a, b) { return a + b; })");QJSValueList args;args << 1 << 2;QJSValue threeAgain = fun.call(QJSValue(), args);
While it should be
QJSValue fun = myEngine.evaluate("(function(a, b) { return a + b; })");QJSValueList args;args << 1 << 2;QJSValue threeAgain = fun.call(args);
