Proposing that C++ acknowledge that there are exactly 8 bits in a byte.
I’d love feedback, especially from embedded / DSP folks who think this is a terrible idea.

P3477R0: There are exactly 8 bits in a byte

@jfbastien What about weirdass old systems, too? I guess that's similar to embedded.

@IceWolf they use C++26?

@jfbastien Good point, still though.

It also limits anyone wanting to build new Weird Computer Architectures.

@jfbastien Though, on the other paw, if specifying it gets compiler makers to stop making weird assumptions around it for ✨OPTIMIZATION✨...

@jfbastien but like, ideally the fix for that is more to get compiler makers to not do quite so much "it's undefined behavior so we can do whatever we want!", and less "you're not allowed to use C++ on wonky architectures". I would think.

But we've never even used C++ yet (only C), never ran into the weird UB things people complain about, and so yeah, no personal experience with this stuff.
