I've handled this a bit differently. Since this will be the same regex for each module we dump, I've done the validation up-front (next to the other checks), and changed this into an assertion.

Done. I've made the individual functions return an `int`, and had `main` forward that. The reason I am not having the functions return an `Error` or like is that the functions generally do the same thing over several inputs, and the errors that happen when processing one of the inputs should be printed next to that input and not deferred until the end. So, the functions just accumulate a flag saying whether they encountered any errors and then return that.
