{
    // TODO: Argument validation
    Where first = conditions.get(0);
    Where second = conditions.get(1);
    List> rest = conditions.subList(2, conditions.size());
    // You'll to suppress a warning here due to generics...
    Where[] restArray = rest.toArray(new Where[0]);
    target.where(first, second, restArray);
}
