> Optimal reading width is like 40-90 characters That statement follows along the same line of thought that many people that want 80 char lines have. That it's better because "it's optimal". I have yet to see any significant study actually showing this to be true for the case of something like code. Personally, I like longer lines where they make sense, and shorter lines where they make sense. But overall, I like a line configuration that lets me understand as much as possible with one screen of lines. That's the same reason I prefer short functions, because I can understand more in the same screen space from a single function call (by the name) than I can if the same code is inline.
