https://docs.rs/grounded/latest/grounded/uninit/struct.GroundedArrayCell.html is essentially the "pool storage", you could do a lot of productive damage with:

```rust
struct Pool<T, const N: usize> {
    used: [AtomicBool; N],
    storage: GroundedArrayCell<T, N>,
}

impl<T, const N: usize> Pool<T, N> {
    const fn new() -> Self {
        Self {
            used: const { [AtomicBool::new(false); N] },
            storage: GroundedArrayCell::uninit(),
        }
    }
}
```
