I've done that and called the counter option --for-real, but I'd like both args so runbooks can spell out:

    1. do-step-one --dry-run
    2. (do validation)
    3. do-step-one --real-run
    4. (do validation)

Many commandline parsing libraries assume you're doing booleans, and I think --dry-run and --no-dry-run is confusing. And, internally, you have a boolean flag so there's always the possibility of some code getting it backwards.

Internally, I'd like an enum flag that's clearly dry_run or real_run, so the guards are using positive logic:

    switch(run) {
      case dry_run:
        print("Would do this...");
      case real_run:
        do_real_thing();
    }
