The reason this wasn't done by the standards committees is that they spent decades refusing to admit there was even a problem they could help fix. And if there was a problem, it was easily avoided by just writing better code. And if writing better code wasn't enough, well it was certainly too expensive to provide as a debug option. And if it wasn't too expensive to provide as a debug option, the implementors should really lead the way first. And on and on.

The C committee at least seems to get it now. The C++ committee still doesn't, led in large part by Bjarne.

This is a misrepresentation based on a misunderstanding on how standardization works. The C standard committee has long recognized the need for better safety and carefully made it possible so that C could be implemented safely. But the process is that vendors implement something and then come together during standardization so that it is compatible, not that the standardization is the government that prescribes top-down what everybody has to do. Vendors did not bother to provide safer C implementations and safety features (such as bounds checking) did not get much attention from users in the past. So I am happy to see that there is now more interest in safety, because as soon as there solutions we can start putting them into the standard.

(We can do some stuff before this, but this is always a bit of a fight with the vendors, because they do not like it at all if we tell them what to do, especially clang folks)

Stop mixing C and C++, tons of people on Unix still hate C++ (Motif a bit less) for being un-Unixy and megacomplex, even more today. Die had Unix and C people created Plan9 and now Go, which is maybe the other succesor to C before Inferno and Limbo, where programming it's more simpler than the whole C and POSIX clusterfux (even Plan9 and 9front itself can be called a "Unix 2.0").

C++ is something else. Heck, it's often far more bound to a Windows domain (and for a while Be/Haiku) than Unix itself by a huge stretch.

It is probably worth noting that C++, like C/Unix, originated at AT&T Bell Labs and was originally referred to as "C with classes." Classes were implemented using a preprocessor.

Unix creators called Unix "dead and rotten" because the eulogy was done by Perl, and Plan9/9front and Inferno obliterated it. Ditto with C+POSIX against Plan9's C (and 9front) and Inferno vs Limbo, the grandparents of Golang, which is seen from Pike and so as the tool set C++ should have been.

Golang it's like Windows NT. C++ it's like Windows ME, it might have their cases on RT performance and multimedia because of having far less layers than NT, (and much better on single core), but it crumbles down fast and it was really easy to shoot yourself in the foot. Windows 2000 and XP killed it for the good.

Some day Golang would be performant enough (even with CSP) with multiple cores so all the 'performance' advanteges -suppossedly C++ brings- aren't needed at all.

Even C# can be as good as C++ today in tons of cases (AOT and emulators like Ryuyinx are not a bluff), even SBCL for Common Lisp too if you finetune the compiling options.

To clarify, I do agree with you that C and C++ have been two distinct languages for a very long time. And C++ doesn’t have much in common with POSIX.

What I disagree with is the idea that C++ was developed completely independently of C (and Unix) - it originated at Bell Labs and was initially just an extension of C with classes. If you looked at the document I linked to, you would see that Bjarne Stroustrup thanks Dennis Ritchie in it for being a source of good ideas and useful problems. I don’t think I need to explain who Dennis Ritchie was for C and Unix.

I agree, but are you responding to me?
Yup, and its not just the standards committees. Look at TR 24731 as an example, an absolute no-brainer for security adding (shock, horror!) bounds checking to long-standing trouble-prone APIs that's been around for 20 years, and the response from most compiler writers/library authors has been "lalalalala I'm not listening I'm not listening". Even then it only got as far as it did due to relentless pressure from Microsoft, anyone else and it'd have been rejected outright.

Having said that, some of it may be due to "it's from Microsoft, we can't ever use it". I'm actually surprised not to have seen any anti-MS diatribes in the discussion so far.

Despite all security denial attitude, WG21 is doing much better than WG14.

Still looking forward to the day C supports something like std::string, std::string_view, std::span, std:;array.

Which starting with C++26 finally have a standards compliant story about having bounds checks enabled by default.
