Such hypotetical idea used some years ago in other context, swapping between
two populations comes mind. Quite extreme is do changes for other and read
Also was there earlier something about factory pattern and trying own
resycling impl, this can be outdated opinion but if I remember right own
re-use pattern can be made quite fast.
