Embarrassing admission: for a little while when I first started with Inform 6, I knew so little about text editors that wrote my source code in my then-word processor (not MS Word, but something Mac-specific… MacWrite Pro? something like that. It’s been a while) and then saved as text, which added a fun extra step to each compilation. I’d done other programming before, but always within an integrated editor, and didn’t know what to do when required to produce my own text files.
This said, I think I agree with Pacian. If someone is frightened off by “we use this other tool because it handles the special requirements of this work better”, what are they going to do when they hear about variables and loops?
