> Zig vs Rust also shows up with how object destruction is handled.

I often hear critiques of Drop being less efficient for anything Arena-like, where batch destruction would be better, and holding that as the reason defer is a better approach. What is not mentioned there is that there's nothing stopping you from having both. In Rust you can perform batch destruction by having additional logic (it might require control of the container and its contents' types for easiest implementation), but the default behavior remains sane.
