I'm sorry, you're right - I meant to modify the example the way you did, to
check if it works or not. But for some reason I just made it run (which was
more work than expected due to embedded unicode spaces) and then forgot to
actually do what I wanted - remove the (object).

And then it doesn't work, as you correctly observed. Sorry for me beeing
confused.
