I agree that this is a nice thing. A similar phenomenon happens in Python. There, the trailing comma on a final item is mostly optional, but I usually put it in

I agree that this is a nice thing. A similar phenomenon happens in Python. There, the trailing comma on a final item is mostly optional, but I usually put it in regardless. Occasionally I have to deal with similar code in C++, and it's always just a bit annoying. I'm reminded of how refreshing it was to move from Pascal to C 'waaaay back when. Among other things, I could now end every statement with a semicolon, no matter what. Little (and big) changes in syntax that make life easier for the programmer are worthwhile. Language designers, let's pay attention to these things!
