Miyako, I've taken to always specifying the type when I use OB GET except in cases like copying a key from one object to another. I like that OB GET doesn't throw an error when it's typed and the key doesn't exist.
It would be interesting to hear about how they are able to parse mixed type json arrays sometime, as I think about a little more.
