Far be it from me to disagree with Kernighan but... when I think of "clever" code, I think of things like Duff's device. That's clever as hell. It's also perfectly debuggable. When I deal with undebuggable code in the wild, it's usually due to people doing things like declaring global (sorry, "public static") variables that connect to live databases and start downloading definition tables into memory before the code can run.
