Interesting. I've last had to deal with formal grammars in the previous century, and your post had me go scratch the surface of what PEGs are. If I understand correctly, your example is not a well-formed grammar, because of the left recursion. So what you're saying is that PEGs align badly with our expectations, tempting us to create non-well-formed grammars, and making it hard to recognize them as such, because our brains want to parse them differently. Right?
