   So if nothing moves, you can't make an array that grows?

      It appears they got around that by making expanding and contracting data arrays builtin types the compiler impls. And it does this by creating what they call a "data stack" for each thing that needs to grow. To me it reads like "we have a builtin type that hides the heap allocation and does the free at the scope exit ", which is fine I guess as it keeps the nature of the language in tying lifetimes strictly to function scopes.
