So far the (()) seems to be a decltype only thing, so this would be a frontend bug. > >> El 30/7/2015 11:06, escribió: >> >> I don't it's a language issue: https://ideone.com/k1vz5d >> >> El 30/7/2015 10:51, "Gedare Bloom" <ged...@gwu.edu <mailto: ged...@gwu.edu>> escribió: >> >> OK, I guess this makes the convention "minimize parentheses" mandatory >> if we want C++11.
