I love this! I wish it existed back when I was writing my first memory allocators in university or when building a custom EntityComponentSystem implementation. I'd love to also see applications of custom memory allocations. I know about usecases in building game engines and the importance of hitting cache there, but I'm not sure where else in the world this would be as useful.
