It's not just allocation: if it didn't get garbage collected, then there is *at least* one reference to it that needs to be updated.

which reference is that?. Immutability means that old data can't reference the new one, right?. What kind of reference (apart from live data on the stack) can we have on new data on the nursery?

So what happens when there is more than one, and some of those are active in other threads?

Same as before right? Sorry, maybe I don't have the right mental model. If you could show me a general picture of what happens when a nursery gets full I would appreciate it :-) . -- Ruben Astudillo
