I was talking about the fact that Guido's 'Just use "+"' suggestion is insufficient, because it requires adding extra parentheses. Therefore, the problem we're trying to solve is 'member-dot and % both have higher precedence than +.' Your '"+" has a lower precedence than "%" and attribute/method access' means the exact same thing, just stated in the opposite order. 

So… I think I'm missing your point.
