Like I said, it tried to be an answer to similar problems, yet it failed. By the logic of C-for-all creators, Cyclone falls into the “evolutionary approach” group. Why Cyclone did not succeed in spite of “revolutionary” languages with similar aims gaining traction is what I don’t quite understand. I have never had any occasion to try Cyclone though, so I’m only basing my assumptions on what other people were saying about it. Still, its design appeals more to me than, for example, Rust, because ability to include C headers directly is IMO the very essential thing necessary to productively rewrite an old codebase.
