Hm, without thinking too much about it I'd say it's okay to change the evaluation order.
Do you mean the option 3, right? This is the simplest option. I have already wrote a PR for optimizing old-style formating , but have not merged it yet due to this change of semantic.
I can't imagine (non-contrived) code where the fact that a is formatted before b is evaluated would matter, so I'm fine with option 3.
