/**
 * pack every property item of source list into an any entry of destination list
 * Resulting list will have follow format then: "sequence< Any(PropertyValue) >".
 * If one item couldn't be converted it will be ignored - means target list can
 * be smaller then source list. Source list isn't changed anytime.
 *
 * 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
 *          of destination list at the end of it only.
