I would also favor the minimalist/traditional/like-everyone-else approach. I wondered at first if open/closed boundaries made sense, but on consideration, that's not what clamp() traditionally does. It's just min/max shortcutting. So let's just do min/max shortcutting and move on with life. --Larry Garfield
