DeVault: Announcing the Hare programming language

DeVault: Announcing the Hare programming language

I think you're taking this the wrong way - the point is that C programmers value the fact that C someone wrote 30+ years ago is still useful C far more than they value any new language feature that's not in C2x (or often, C99 or C90).

As a consequence of this, the bar for "new language that will attract people away from C" is very, very high. The natural instinct of the remaining people who prefer C when faced with a new language is not "oh, that feature is awesome and I will switch language to get it", but "will that language still be usable in N decades time? Can I implement the feature usably in a C library?".

If you do value that long-term stability over the language features, then a new language aiming to attract you has a big hill to climb - being new, it can't point to 30+ years of history like C can, and so how can it convince you that code written for the language as it exists today will still be useful code in 30 years time?

After all, we've established that that's a big chunk of why you use C - because you've seen so many attractive languages come and go in C's lifetime, and you don't want to start a project today that'll be impossible to compile (let alone use) in a decade. And that's a perfectly good reason to prefer C - it's the same reason that a lot of physicists prefer Fortran, because they want their code to still work for cross-checking results decades after a 20 year experiment comes to an end - but it does make it hard for a new language to attract you away from C.
