C++ has way more resources than almost any other language. There are or were teams from Microsoft, Google, Apple, and Bloomberg who work on the compiler. Lots and lots of man hours have been spent and I’d say wasted. The problem is C++ the ISO committee and that is the language essentially.

They had a chance in c++11 - we’re going to make a modern c++ that fixes the old problems. And for a time that was true. But they’ve completely lost their way again and getting caught flat footed when the US government recommended people stop using c++ and instead of figuring out how to fix the language they doubled down on unworkable ideas that don’t meaningfully improve the situation.

I think the advice will be to run fil-c in production and then c++ will have an issue as to just what it’s identity is because in practice it will be significantly slower than alternative approaches.
