Thank you for the elaboration. Now that you remind me, I remember about the C11. Which also adds "The C memory model" as part of the runtime, IIRC. Other languages have different memory models. Usually simpler, though it's hard to hold that against C11 since it was in the unenviable position of trying to codify decades of implicit and divergent practice in one of the trickiest places in software engineering.
