It doesnt. Processes can share memory

I think I'm missing something; neither zig nor rust are GC languages. Did bun originally start off in javascript or something, and the rewrite you're referring to is from JS to zig?

> It's ludicrous to claim that they have some kind of reasoning ability.

Did you read the post that you're commenting on?

It seems wholly believable to me that they are narrow intelligences that are great at some kinds of reasoning and worse at other kinds. Obviously they can reason through problems that most adult humans can't solve

Sorry if this is a dumb question but wouldn't vector and vector generate different code on get/set? Since floats go in different registers/need different instructions to load/store them to memory? Or is it something like, actually all of the std::vector functions technically operate on T&, and manipulating the pointers can use the same code, and really it's the optimizer that has to think about float vs int registers or something

By default in oxcaml, "stack" / local allocations happen in a separate stack on the heap (which the runtime allocates for you). If you allocate enough to exceed that capacity, it will resize it dynamically for you.
