with-input-from-file doesn't exist.

[johannesCmayer]

I think this code should work (it works in chibi) but in drracket I get advent_2.rkt:7:3: with-input-from-file: unbound identifier in: with-input-from-file #(91 20)

The weird thing is that drracket still provides a completion for it. Probably I am just making a very dumb mistake.

#lang r7rs

(import (scheme base)
        (scheme write))

(define main (lambda (args)
  (with-input-from-file "data.txt"
    (lambda () 
      (display (read-line))))))
