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))
