If a key equivalent to the specified key already exists in this map, return a pair containing an iterator referring to the existing item, and false. Otherwise, insert into this map a newly‐created ENTRY object, constructed from std::forward<KEY>(key) and the specified args, and return a pair containing an iterator referring to the newly‐created entry and true. This method requires that the (template parameter) types KEY and VALUE are emplace‐constructible from key and args respectively. For C++03, VALUE must also be copy‐constructible.
