And just in case you don't already use a text editor that indents
Lisp/Scheme properly, please try to find one (or do it manually).
It will make your programs *so* much more readable to others:

    (define list2string
      (lambda (list)
	(if (= (length list) 1)
	  (symbol->string (car list))
	  (string-append (symbol->string (car list))
			 " "
			 (list2string (cdr list))))))

[Yes, I know, some people prefer all three args of an "if" to be
indented the same. But I don't.]
