Perl is different as people really tried to do this on purpose with maximizing the concept of one liners. Maybe it's a PTSD kind of an effect? "Any" code or good code doesn't try to be developed in a way that is difficult to parse by the next person. Perl developers definitely didn't adhere to the policy of writing code like the person maintaining it is a serial killer that picks people that write unmaintainable code and they know where you live.
