Argh, I deserve my portion of lashes, but it is so clearly standing in my experience: most coders who don’t care of syntactical purity like formatting, indenting, consistency, meaningfulness etc. — they have less awareness and make more errors than those who do. It is not a strict rule, but a sign of weakness in that regard.

  }
  int foo(){
    for(x=1; x<len*2;x++){//over 2 array len
    ...(no empty lines for next hour)

I know I’m clinical perfectionist, but try to see it behind my complaint. Our brain can process only few things in parallel. If you overload it with parsing and do not provide hints like grouping and/or formatting, you occupy a couple of threads for a complete bs. As if programming was not one of the hardest things already.
