file->lines is also quite useful

Anyone with Racket CS 7.5 installed? I got a bug report. Does the this run in DrRacket CS:

#lang sicp (/ (+ 5 4 (- 2 (- 3 (+ 6 (/ 4 5))))) (* 3 (- 6 2) (- 2 7))) https://github.com/sicp-lang/sicp/issues/32

No, it runs out of memory, so something is clearly wrong. Works fine in traditional DrRacket and with just Racket CS.

Just -37/150 goes wrong in DrRacket CS, so it’s almost certainly something triggered by trying to format a fraction.

There is not much going on in the sicp lang.

(define-syntax module-begin (syntax-rules () ((_ . forms) (#%printing-module-begin (module configure-runtime '#%kernel (print-as-expression #f) (print-pair-curly-braces #t) (print-mpair-curly-braces #f)) . forms)))) https://github.com/sicp-lang/sicp/blob/master/sicp/main.rkt

Yes, I mean it’s unrelated to the sicp language.

Check.

Repair pushed.

Thanks!
