Checked C
I don't expect it to get traction.• C is valued for being super portable and compatible with every platform, including legacy ones, but this applies to specifically C89 or C90, and nothing else. As soon as you embrace new features, it's not your universal C any more. You're going to need newer compilers, new tooling, and that's almost like starting with a new language.• C users have mostly self-selected themselves to like C the way it is: a small, flexible, zero-overhead language that isn't C++. Addition of checked containers, generics, and restrictions on pointer arithmetic, etc. make checked C not feel like C any more.• Checked C still needs refactoring of the code. For large established codebases this is still a lot of work, and still a risk of introducing new bugs. It's very tempting to settle on just running one more analyzer, sanitizer or fuzzer instead.And in the end with all this effort, back-compat break, whole-codebase refactoring you're still left with the old C, with headers and include paths, sloppy macros, ancient stdlib, painful dependency management, etc.If you're going to rewrite C incrementally to a more complex dialect, and require a newer non-standard compiler for it, you may as well run c2rust on it first.
