Just a tiny bit faster, but really "simpler" might have been a better description. It won't get confused if someone (re)blesses the array, for example. It will (probably, as I said) be slightly faster because it doesn't even have to look up blessedness and put that into the string and it will use a shorter string. *shrug*

It was a quick note I added at the end. I prefer 0+$ref over "$ref" in general. But the speed isn't really the point. Just not doing extra work that might get in the way.
