Sorry for reviving an old thread. As someone who did a lot of programming
competition in the past, I can totally see why IO in Racket is difficult. As
mark.engelberg said, the goal is to solve as many problems as possible. After
the competition is over, it's over. No one is going to care about

of a function that is program-local
(define size (file-size "/some/path")) ; result of a
function that touches the disk, but result never used
