I was looking into this as well, it seems that Goose does not support having a dynamic number of resizable values, but it does support having a dynamic number of dynamically sized value.

In Rust parlance this would be the difference between a `Vec<Vec<T>>` (many `Vec`s, each can be resized) and a `Vec<Box<[T]>>` (many `Box`ed slices, each with a dynamic size, but none of them can be resized).

I bet you can exploit dynamically sized values to rebuild resizable values, with the downside however that you'll likely leak their memory until you exit the current scope.
