I don't think I was clear above. I want embedded objects. I wish there was a more "database-native" way to do it than using JSON, and all the ugliness that JSON brings. (Like dynamic typing, schema-within-a-schema, more complex indexing & querying, etc.) Sounds like something the databases should be able to provide natively, without needing to use JSON at all. (And apparently support for this sort of stuff is slowly improving! Thanks to all the sibling comments for details!)
