This article reminds me (on the surface, this is deeper than my experience) of how the recent Goose language orients things.
I never worked with it but I seem to recall the old original Mac API's (Pascal based) used "handles" a lot to solve the issue of being able for the system to move allocations and memory out from under a program without it knowing, as a "pointer to pointer to <thing>". I was poring over those manuals in ~1988/1989 with visions of being a full-time Mac developer in my head.
I remember back in the day in Windows C++ programming everything was a HANDLE memory is probably not serving me, but they were all really just void* renamed. And you use them with various win32 functions I guess to keep things straight. I don't miss those days.
and why game engines use entity-component systems, analytical databases are column-oriented, etc. That is, the classical organization of "objects" as structures has a lot of overhead when you're doing heavy work. For instance java reifies objects with a big header, a monitor lock, and other stuff that really adds up if you, say, are writing a chess engine and need to maintain transposition tables. And even if you are in C++ and there is a lot less overhead, AoS still has bad mechanical sympathy compared to SoA.

A nice analysis of large-scale programming techniques that go beyond the novice version of "OO Sux" to the almost secret
