“C3 is what C would look like if you redesigned it today with everything we have learned in the last fifty years.”
Yet another systems language trying to occupy the C-but-modern niche where Zig, Odin, and Hare all live. The pitch is reasonable. The chance of any one of these languages reaching the critical mass to matter outside hobby projects is low. The good ideas will get absorbed into Rust or back into C. That is how this category works. Watching the experiments is still worthwhile because the next mainstream language draws from this gene pool.
