Memory ownership
When a stack frame is exited, its local allocations are all released, and its references to boxes are dropped.
For now, this reference is a best-effort document. We strive for validity and completeness, but are not yet there. In the future, the docs and lang teams will work together to figure out how best to do this. Until then, this is a best-effort attempt. If you find something wrong or missing, file an issue or send in a pull request.
