if i miss a quote in json, it’s an invalid file. I fix it and move on. Maybe just pass it through a beautifier or something.

if I mess up indentation in yaml (which can easily happen after a copy and paste), I get a valid file that means something completely different. And no beautifier can help with that, because it’s a valid file. I have to look really closely to find the error, because tools can’t help. And when I do, I usually have to change multiple lines, instead of just adding a comma.
