Ok, thanks for posting that code.
Do you expect modules to be re-invoked on every require? I am trying to
understand your concern about "valid behavior".
The model I have with regards to modules is this: modules can be "required"
from many different modules, but they are "invoked" just once.
So I if I have files A.rkt, B.rkt, and C.rkt, which all look like this:
;; a.rkt
#lang racket
(printf "hi, this is A\n")
;; b.rkt
#lang racket
(require "a.rkt")
(printf "hi, this is B\n")
;; c.rkt
#lang racket
(require "a.rkt")
(require "b.rkt")
(printf "hi, this is C\n")
Then I expect to see the following output when I run c.rkt:
hi, this is A
hi, this is B
hi, this is C
Does my expectation surprise you, or does this match what you'd expect as
well?
