Morning, Just to chime in ... can you split the PR into the RFC, and the new thing please.
Just another question on how we could make objects that have count_elements (which is in object handlers) implement an interface on the class entry (which is detached from handlers) ? I'm sure it's doable, but it doesn't look very straight forward, some kind of hacking in instanceof maybe ... not sure ...
