New Data Structure Every Programming Language Will Have
It is called MultiArrayList, which represents an array of structures as a structure of arrays

Obviously that requires a either a novel type system and or compiler support.
So the only language supporting it is Zig, which is a Rust clone.
But in a few years it will appear in C/C++/C#/Java.
It is useful since it allows optimizing existing code with a single type change.

Basically poor muslim's ECS.
