Is there a standard way of moving a range into a vector? http://stackoverflow.com/questions/10720122/is-there-a-standard-way-of-moving-a-range-into-a-vector v2.push_back six for_each v2.begin v2.end v1 string s v1.emplace_back std move s This performs a successful move but doesn't.. On an obscure point I'm pretty sure that vector insert can emplace from the source which is irrelevant here since the source is.. since the source is the same type as the destination so an emplace is the same as a copy move but would be relevant to otherwise..
