You're missing the point. Volatile forces two loads of a value that may have changed in the middle. So the value of "x" may depend on the time/order of load.

Open source and free software isn't the same thing. Nobody made a claim on Java either, until someone did. I just distinctly remember explicitly not exploring D for that reason. Also this way way before LLVM and I also don't think GNU had a D compiler back then. There was only the (and I really believe it was closed source) Digital Mars compiler.

Yeah dude but you've really marketed D poorly. I remember looking at D what must be 15 years back or so? And I loved the language and was blown away by its beauty and cool features. But having no FOSS compiler and the looming threat of someone claiming a patent (back then it was unclear that Mono/C# was "legal" and even Java hung in the balance) was too scary for me to touch it.

Now I'm old and I believe D has missed its opportunity. Kinda sad.

My point is, in your exact example both reinterpret_cast and C-style casts have the exact same behavior, making the example bad. If you want to showcase a deficiency of C++, it would make sense to pick something where the difference between cast types actually matters.

I'm not sure what you're getting at but

const bool z = (const bool)((int8_t)2);

Is perfectly valid C++.

...and an incredibly handwavy shallow explanation of why this actually works ("Through a clever sequence of oblivious transfers and what’s called multiplicative-to-additive share conversion, they each compute a partial signature.")

I don't get it. If you want a blog, write a blog. If you don't want a blog, don't write a blog. But why use an LLM to create a slopblog? It just wastes EVERYONE's time and energy. How disappointing.
