I think even C malloc should be considered pure. True, it affects global state by allocating memory, but it never changes existing values, it just allows for new values. free is pure because it isn't side-effecting, it deallocates what you give it. That's just my perspective on it though, others might have other views on it.
`free` is not pure, because if you have a reference to that memory that reference is no longer valid.
