This trick is very helpful, but I would argue that there are still a lot more parentheses due to almost everything being written as a function in lisp. When I started programming in Racket arithmetic and comparison expressions tripped me up frequently. My tip to beginners in this area would be to use the dot-notation first, then switch to the standard way once comfortable. for example:

    (20 . > . (10 . / . 5))

may be more clear than

    (> 20 (/ 10 5))
