And then there's the fact that the "precedence" is different depending on which meaning the dot gets. Remember that what you're trying to solve is the problem that member-dot and % both have higher precedence than +.
I thought the problem we were trying to solve was that "+" has a lower precedence than "%" and attribute/method access, so implicit concatenation that's followed by "%" or ".format" can't be replaced by "+" without adding extra parentheses.
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.
You said """there's the fact that the "precedence" is different depending on which meaning the dot gets""". My point was that "." between string literals (which is currently a syntax error) would indicate concatenation of those literals, but there would be no change in precedence; it wouldn't replace "+".
