After learned more about Racket, I found a solution to this issue. We can use First-Class Units. For example, we can parameterize a “module” by lambda: (define your-unit@-maker (lambda (x) (unit (import xxx^) (export your-unit^) ;; you code here... ))) (provide your-unit@-maker) Now we no longer need the initial function any more:smile:
