I believe that distinguishing them visually helps readability. Using + for both makes things look more complicated than they really are.
Agreed.
In principle, I'm with Guido on this one. TOOWTDI and EIBTI weigh heavily with me, and I have been bitten by the "sequence of strings ends with no comma" bug more than once (though never twice in one day ;-). Nor do I really care whether concatenation is a runtime or compile-time operation. But vox populi is deafening.... BTW, I see no reason not to optimize "'a' + 'b'", as you can always force runtime evaluation with "''.join(['a','b'])" (which looks insane here, but probably wouldn't in a case where forcing runtime evaluation was useful).
