Just making sure I understand the intent: by destructing Self into it's fields we ensure that if somebody adds to to the Objects struct they will also have to change this line of code and will be more likely to add the necessary support?

Objectscurrently has some implicit invariants that can potentially lead to data being silently dropped if you're not aware of them.This PR makes sure to check those invariants at compile time.
