Here we go! * Wider screens let you have several Emacs buffers next to each other. At 80 chars you can have about 2 buffers next to each other on a 13" screen. * The average line length is about 30-35 characters in Python. If it's anything similar in Haskell shorter line length are more efficient, looking how much of the lines times columns space is filled with characters. * The eye has trouble traveling back to the next line if lines get too long (at least when reading prose). Research says around 60-70 characters is optimal, if I recall correctly. _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs
