I kind of agree, yet at the same time, the difference between the two is very small in most cases. So I think it might be worthwhile to look at it instead as making it possible for the caller to give a *hint* about what kind of UI would be best. It might deserve a completely new function to replace `completing-read`, but I think it would be good to make this new function such that it makes `completing-read` obsolete. Stefan
