There's RustPython and far more compatible than IronPython back in the day. C++ is NOT an extension of C, they diverged a lot. >Codex CLI, uv, ripgrep, and what else? RustDesk, Servo/Firefox, tons of gtk4-rs on Gnome and extra tools, Librsvg, CosmicDE (Fedora Atomic with Cosmic can be slightly faster than vanilla Gnome Silverblue), Ruffle, Gopher64, ArtCraft (both the vibecodec cr*p and the AI powered magical multimedia IDE doing crazy stuff which is fine). Oh, and Harper to sharp your English skills: https://github.com/automattic/harper IronCalc looks better than LO Calc performance wise: https://github.com/ironcalc/ironCalc Gnome might be a Rust domain tomorrow and nobody would bat an eye. Fedora/RH/IBM can rewrite the Anaconda installer in Rust in no time.

When you do writing as a form of art, rules are meant to be bent or broken; it's useful to have the ability to explicitly write new ones and make new forms of the language legal, rather than wrestle with hallucinating LLMs. When writing for utility and communication, though, English grammar is simple and standard enough. Browsing Harper sources, https://github.com/Automattic/harper/blob/0c04291bfec25d0e93... seems to have a lot of the basics already nailed down. Natural language grammar can often be represented as "what is allowed to, should, or should not, appear where, when, and in which context" - IIUC, Harper seems to tackle the problem the same way.
