> Initial DML implementation does not allow to UPDATE columns that correspond to key or
its fields - direct modification would probably damage the index as well as hash map integrity,
so UPDATE for such cases would need to do first {{remove}}, then {{put}}.
> In the course of review, it has been agreed that this feature will be implemented in
later releases shortly to deliver initial implementation on time.
