I think the line kinda blurs here. This would be a feature of a core
data type, and in CPython, it would be implemented using a slot
function in dictobject.c. But it doesn't need any syntactic changes.
Are the core data types part of the language or the standard library?
In any case, it doesn't much matter. The backward compatibility
considerations would be the same either way, and this would mostly be
used with literals and immediate unpacking.
