[IlliOnato]

This is an argument to keep the comments short and to the point (preferably one-liners for code paragraphs, longer for functions themselves), not to skip them altogether. Then both checking them and updating them becomes less of a burden.

I even find "man with two watches"useful. When I see it, I _know_ that something is wrong here, and it's worth checking. Most of the time the comment is found to be "buggy" (and gets updated), but I have found quite a few real bugs in the code this way.
