Format of Applications

• Scheme does not care how you type an application, so long as it is a correctly parenthesized list

• The following are equivalent expressions:

      (* (/ (+ 6 11) (- 46 4.5)) (/ 7 9) (+ 10 23 (sqrt 4)))
  
      (* (/ (+ 6 11)
            (- 46 4.5))
         (/ 7 9)
         (+ 10 23 (sqrt 4)))  

• The second form is far better for human readers.
