}

let mut array = uninit_array::<String, 10>();
array[0].write("A".to_owned());
array[1].write("B".to_owned());
array[2].write("C".to_owned());
array[3].write("X".to_owned());
array[4].write("D".to_owned());
array[5].write("E".to_owned());

    let elt = array_remove(&mut array, 3, 6);
    assert_eq!(elt, "X");

    let init = &*(&array[..5] as *const [_] as *const [String]);
