I didn't understand that blog post very well, but it made me think of "generational arenas"[0], and I'm curious how they compare? Generational arenas sound similar because they involve passing an index around instead of a pointer, are designed to handle many small self referencing "objects", and are popular in games, so in my mind they seemed similar.
