The code referenced here is extreme. It does not consider diminishing returns or acknowledge tradeoffs in readability. I would advise a more balanced approach. A more compact style allows more code to be viewed at once making it easier to understand. Of course, taken to the other extreme, overly compact code becomes hard to read. It's called, "the art of computer programming", because blindly applying programming principals rarely yields good results.
