[問題] 能否從std::map推導出所需要的std::pair type?
比方說我們現在有一個map
typedef std::map<std::string, callback> CB_MAP;
能否從CB_MAP推導出需要的std::pair<std::string, callback>?
類似
typedef CB_MAP::???? CB_MAP_PAIR;
CB_MAP map;
map.insert(CB_MAP_PAIR("hello world!", somethingCB));
而不用
map.insert(std::pair<std::string, callback>("hello world!", somethingCB));
我是有看到一個名字看起來很疑似的
std::map::_Pair_alloc_type
不過顯然這個一來是內部用的 二來他也不是std::pair
有什麼方法（除了macro以外）可以從std::map推導出pair?
畢竟連iterator形態都可以推導出來了，STL應該是有放個能推導pair的才是吧 =P
