But I'm thinking of ways to make one inherit the other. I like inheritance between modes, but I recommend that you never inherit from a "normal mode": modes should be either designed for inheritance (`prog-mode`, `text-mode`, `special-mode`, `tex-mode`, ...) or be actually used in buffers, but preferably not both. So better create a "c-like" parent mode from which both `c-ts-mode` and `c++-ts-mode` inherit than have one inherit from the other. Stefan
