IIUC the interpolated string F"$ This is $i and this is $s." you are proposing is syntactic sugar for << "This is " << i << " and this is " << s << "." The transformation has the advantage that the result is already parsed. However, if we want to manage with internationalization I believe that=20 the whole interpolated string should be translated to something like format(translate("This is {1} and this is {2}."), i, u); Where translate takes care of the internationalization, it would lookup=20 for the translation "This is %1% and this is %2%." in its dictionary. format is a variadic variant of Boost.Format, which could be more=20 efficient than the use of % as in , format(translate("This is {1} and this is {2}.")) % i % u; This is the schema used by Boost.Locale. IMO any internationalization=20 solution must pay at run time for the look-up and the parsing. Why not have both using two different prefixes for two different=20 translation schemes? I"$ This is $i and this is $s." I recognize that a internationalization solution is more complex than=20 what you proposes and need much more than that. Your proposal has enough=20 value by itself, and could be adapted later if one day we have an=20 internationalization proposal. Vicente P.S. As others, I don't think it is correct to have the fist << in the=20 translation, the translation should result in one expression. --=20 ---=20 You received this message because you are subscribed to the Google Groups "= ISO C++ Standard - Future Proposals" group.
