At the end of the day trees are still stored linearly in memory. Think of it as an array, with each node an element of the array, and indexes used rather than pointers.

Plenty of trees only ever grow. And that's the normal type of array in Goose. However you can also have arrays that can grow and shrink, if you have a tree that is constantly in flux.

Either way it'll be one stack for an entire tree.
