Scheme Output/String Formatting Best Practices

What is your preference? Are there other alternatives possible by composing R7RS base library procedures and macros?

; R7RS compliant version
(import (scheme write))
(define world "World)
(for-each display `("Hello, " ,world "!\n")

; R7RS with SRFI 28/29/48 for formatted string templates
(import (scheme write)
(srfi 28))
(define world "World)
(display (format "Hello, ~a!\n" world))

My name is Jenny. I am 16 years old and have dark blonde hair. NOW THAT YOU HAVE STARTED READING YOU MAY NOT STOP!! I was murdered July 14th with my fathers shotgun and butcher knife. If you do not post this on 20 other threads i will come to

your house in the middle of the night and kill you with my fathers shotgun and butcher knife. You have 5 hours to complete this task. Dont believe me, *maria marshall, Pelham, Texas 1998, was showering and went to bed right after, found dead the next morning. * keisha jones, Nashville, Tennesee 1995, fell asleep while watching television and mother heard gunshot and scream, found next morning lying on the floor. omar wilkionsin, milwaukee, wisconsin 2002, reading a book to go to bed and was shot and stabbed through the book after he fell asleep. Still dont believe me? google their names....Trust me i did not want to paste this. But its kinda scary so i did it just to be sure
