Ah, yes. Thank you. So it works in CPython 2.7. But I'm curious, does it 
work in very old versions?
I'm not saying that this is important, because language changes always 
are for new versions. However, Anders' claim that this not a language 
change seemed too broad to me.
It may be that this change has very little cost, but it should not be 
dismissed.
