"It was hard to write, it should be hard to understand." (I was joking, of course, when I said this.) It seems to me that that's a reasonable metric for determining if something was well written or possibly well commented. I had an opportunity to go back to some of my older code about a year ago. It was scary to me what portion of it I no longer understood. Worse yet, portions of it referred to documentation that I could no longer find. The company had migrated their documentation through several storage organization technologies and no one seemed to know where the old stuff went. Luckily I ran across a retired engineer who recalled where a lot of it had been archived. (Unrelated) When I read the article, the first thing I thought was that all of the simple programs had already been written.
