Just adding checked arrays would make a big difference I feel. Maybe it's not too late to change culturally, I think both GCC and LLVM has compile options for that.

I also think if Pascal existed with a C syntax front-end, 0-index arrays and ditching the Pascal libraries and going for libc by default, I would probably have switched.

This one thing https://digitalmars.com/articles/C-biggest-mistake.html would have helped a lot. Imo given 1) GCC and LLVM have had extensions like that for a long time now, 2) most arrive at that/similar destination at some point (b/c it's so useful), and 3) afaik standardization was supposed to standardize current best/popular practice that is widespread but non-standard (and not invent new untried untested stuff), I think that C standardization committee dropped the ball (and kept dropping it for a very long time) as far as C arrays (and matrices and ndarrays etc) go.

> going for libc by default

I understand this isn't relevant to the original discussion since the kernel doesn't use libc, but in userland, the flawed design of libc is as much a liability as the language itself IMHO.

For example, maybe you know when to use strcpy(), strncpy(), strlcpy(), memcpy(), but TBH I don't remember the appropriate contexts to use them and I don't write enough C code to warrant actively keep all the nuances in my head.

>0-index arrays

On each pascal array you specify both bounds.

So nothing stops you from doing `array[0..4] of Integer` or whatever.

I mean, in some sense it's never too late to change? But I do think that as technical people our profession has a strong tendency to underestimate (and undervalue!) the social component of this kind of change. If you have agreement on a path forward, getting it done is mostly a question of elbow grease. The hard part most of the time is getting an agreement on which path to choose out of many mutually exclusive options. And the Linux Rust effort is a good example of this: I think getting agreement that this is good and desireable is at least as hard as the technical work of writing the code. As the LWN article notes, there's been lots of change in this over just the last few years but there's still quite strong resistance it seems.

That would be Zig in a way, Modula-2 (1978) for C folks.
