The whole "use a different language" argument is not an argument at all, it's just "throw the baby out with the bathwater".

You edited out where I said that I think it's a bug in the C language standard, but one that made sense in the historical setting.

It's also one that could be fixed, assuming several compilers start supporting it as an option, and people start using it.

But saying "switch to Rust" is just stupid. That simply isn't an option in a lot of cases.
