It's the wrong abstraction though and I am kind of not surprised the Bun maintainers went way. The correct abstraction would be to translate into Rust while using `clone` and `copy` liberally and then iteratively converting to a borrowing model. Nowhere at all was an introduction of the `unsafe` keyword needed.
