Why does anyone have to tell people not to do this? How does it enter anyone's mind as a thing to do in the first place? I've been known to go too far to minimize nesting. I get twitchy at the second level. By the third my brain is trying to crawl out my eyes and strangle me, even on code that doesn't have a potential exit point at every level.
