An argument for operators "+" and "-":

Interesting. But that bug potentially exists regardless of what PEP8 says. This seems to me to be something that should be tackled separately. I imagine that there are versions of 'expr2' that makes this a valid and useful construct (which is why it remains) - if I've missed some historical discussion on this then please refer me to it, I'd like to understand what I'm missing on first glance.
