We definitely need better ways to manipulate JSON.

How would this work when you have a JSON array? Postgres array syntax suddenly becoming key/value syntax for JSON seems like a pretty bad idea to me. Could a different syntax (maybe {}) be used instead?

I don't understand why '{}' should be better than '[]' ?

The lot of modern languages doesn't different between arrays and hash.
