[plt-scheme] Re: Problem of type

You might not like the way that expr->string handles strings and  
quotes.  Format provides three choices (one is like expr->string.)   
Below is a comparison between the REPL, expr->string, and 3 uses of  
format:

(require (lib "string.ss"))

(define  list-of-expr '((define a "string") (define b 'symbol) ...))
(define  (display-expr expr) (format "~a" expr))
(define  (write-expr   expr) (format "~s" expr))
(define  (print-expr   expr) (format "~v" expr))

list-of-expr
(newline)
(map expr->string list-of-expr)
(newline)
(map display-expr list-of-expr)
(newline)
(map write-expr list-of-expr)
(newline)
(map print-expr list-of-expr)
