I don't think that's what he means. I interpreted that as criticism to the way your language handles errors. At the very least, there should be some kind of feedback to the user, especially if you're making this with the intention of drawing in non-programmers. After all, JavaScript was invented for this exact purpose...and we all know how many "content creators" and non-programmers are using that...
