Compilation switch maybe? Support both by default, compile with 
-version=DisableUglyFormatStrings to remove the overhead. Document it as 
deprecated, tweak the first revision of TDPL to use the new format 
strings, give it <X> amount of time, make it deprecated etc. Having 
nice2ugly!"" all over my codebase is not a solution.
