 *
 * algorithm:
 *      (a) reserve enough space on destination list for all possible entries of
 *          source list
 *      (b) try to pack every property of source into an any of destination list
 *          (b1) count successfully packed entries only
 *      (c) use this count of packed entries to resize destination list
 *          Because we getted enough space before - that will remove unused items
