[plt-scheme] possibly silly question

(define str "sdfdsf")
(display (string-append "something" str))

;; if you really like the + symbol, define + to do some more locally 

#lang scheme

(local ((define + (let ((+ +)) (lambda x 
                                 (cond
                                   [(null? x) 0]
                                   [(string? (car x)) (apply string-append x)]
                                   [else (apply + x)])))))
  
  (define str "sdfdsf")
  (display (string-append "something" str)))
