True, I guess I was expecting if you were reimplementing these with additional protections, why not add the protection using the custom pointer reimplementations to ensure no use after frees. Seems like a missed opportunity.

I don’t think there is a way to do this generally without GC, and that leads to significant pitfalls anyway (eg in Java you can accidentally end up holding multi-GB strings in memory because a few references to short substrings exist).
