I should have framed my words better, I guess. Rust is a radically different language, and honestly, none of the feature it offers fixes the main issue, that is technical debt - I mean yes, there’s incline C or FFI, but that’s still going to be a radical migration.
What I’m trying to propose is an alternative project, independent from the ISO. Maybe it could be a C-to-Rust, or a C-to-Vale migration project. It could be any of the modern language, I don’t really care. But that particular compiler/transpiler/migrationpiler/<something>-piler should have the ability to do step-by-step migration.
