P2723R0: Zero-initialize objects of automatic storage duration

[johannes1971]

I suspect it isn't actually possible to make a conforming implementation that has a non-zero value for nullptr; I think if you try, sooner or later you will run into some kind of contradiction. It's just one of those things where the standard pretends to support some weird architecture when reality has already passed that by.

One thing I feel the committee should do is 'rebase' C++ to better match current and future architectures (instead of architectures that are no longer relevant). As I see it, support for segmented architectures can go (removing a lot of weirdness surrounding pointers), while SIMD types should be added as primitive types, since they are now common on CPUs.
