I hope circle is the thing that makes the committee realise there is an alternative to their attitude of 'we're not versioning files, we're not giving you opt-in features, we're not giving you new keywords, we're not fixing demonstrably bad and wrong behavior'. But I doubt it. I've been in and out of C++ for over 20 years, and every time I'm 'back', it's the same old tired story.
I'm more interested in Val than the rest, but, Val isn't really a C++ replacement (in terms of syntax, at least), it's a language that offers C++ interop. To quote an old joke 'How do you get to Dublin? Well, firstly, I wouldn't start here'. I'm not sure whether any new language in 2023 should start with C++ interop as one of its main goals.
