That's cool I guess. Modules do have partial support in all the major compilers. I'm not sure what that venn diagram looks like. If you wanna argue that modules are ready for primetime and businesses should start converting their codebases to use them then go for it. But it's a pretty obvious fact that almost no one is using modules outside of hobby projects. I don't think I've seen a single significant C++ based project linked on HackerNews that uses modules. I'm sure a few did and I didn't notice. Header files in C++ are hugely problematic. It's why the module system was designed. That system is not ready to actually be used by the vast majority of C++ programmers on the vast majority of C++ projects. Even if you happen to be using it right now in your hobby projects or even your job. I hope someday modules are ready and make my life better. It'll be a few years at bare minimum. I'm not fully convinced C++ modules will be standard convention 10 years from now. I think there's a real chance they wither and die on the vine. I hope not! But it's definitely a possibility.
