What about using string prefix 'f'?
f"{foo} and {bar}" % something == "{foo} and {bar}.format(something)
s = f"{foo}" t = "%(bar)s" s + t # raises Exception
Transition plan: n: Just add F prefix. And adding "format_string" in future. n+1: deprecate __mod__() without 'F'. n+2: libraries use .format() and deprecate __mod__() with 'F' n+3: remove __mod__()
-1 That requires keeping formatting information around in every string instance. -- Regards, Benjamin
