Looks like the ~90-100% autofree and then reference counting, is a good memory management, and is very practical too, as proved by translating DOOM from C to V and building it in 0.7 seconds, and the demo showing Ved editor compiled with --autofree, running with 0 memory leaks.
And the good thing about autofree is that "The developer doesn’t need to change anything in their code. “It just works” ".
