Going to C++ competitors there is obviously Rust, but also Nim, Crystal, Beef and a lot of others. (And Jai is a C++ competitor too)
This is maybe more striking when comparing against C which was already very old and battle tested in 1989 when it was standardized. If you pick any of these languages you're accepting an unknowable amount of churn. It better be worth it.
C has plenty of issues too, even though it is very old, battle tested and standardized.
(How about all the UB in C, for example?)
That is why people are looking for C alternatives in the first place.
>It better be worth it.
It better be worth it for C too (and for C3; pun unintended but evaluated).
The notable commonality of these "C alternatives" is that they are still moving targets and yet that wasn't mentioned.
It's quite common for a project to pin to a stable version so this doesn't seem too unpredictable.
Asking because my above question and this current post about C3 are related to this recent post by me, which had a good number of comments:
Ask HN: What less-popular systems programming language are you using?
