What arc did you run this on, Pauan? I'm trying to add it to anarki and having trouble with nil-terminated lists and shuffle:

  arc> ($.shuffle '(1 2 3))
  sort: contract violation
    expected: list?
    given: '(1 2 3 . nil)
    context...:
     /home/agaram/.local/racket/collects/racket/private/list.rkt:43:2: sort7
     /home/agaram/Desktop/s/anarki/ac.scm:1215:4
(The require seems unnecessary on anarki.)

I used Arc/Nu (https://github.com/arclanguage/arc-nu).

It seems the problem with Anarki is that Arc's lists are terminated with the symbol 'nil rather than Racket's null. So you have to convert from Arc lists to Racket lists (and back again). Here is the relevant code:
