I understand how to get array data out of a function.

This breaks the abstraction and is also monstrously inefficient.

Imagine that objects are modeled with associative arrays. Now you have
to copy every time you want to simulate returning an object
from a function.

If the objects are treated as having mutable properties, the semantics
is wrong. You can't return an object by copy if you need the caller
to be able to mutate the original.

No, it doesn't, sorry.
