Why Strings as Classes?

Its code:

final Ref nth (int n) {
    auto p = this;
    for (int i; i < n; ++i)
        p = p.next;
    return p;
}

If the usage patterns show this is positive, then a static pointer/index pair may be added, that keeps the last accessed pointer/index, this may speed up things if the items are accessed sequentially, or even if they are accessed with some several forward skips, avoiding starting from the beginning each time :-)
