Yes, the indirection (and also late binding) is why hot reloading is (somewhat) ergonomic in those languages, but would be difficult to do in Rust (or C++, etc)

Yes, the indirection (and also late binding) is why hot reloading is (somewhat) ergonomic in those languages, but would be difficult to do in Rust (or C++, etc). I think the shared library types would need to be indirected either via compiler support, or some kind of `Hot<T>` wrapper that acts like a `Box<T>` when hot reloading is enabled, and like a `T` in "production" mode to be ergonomic.
