:relfileprefix: ../../
:mrdocs:

Insert into this unordered multiset a newly created `value_type` object, constructed by forwarding `get_allocator()` (if required) and the specified (variable number of) `args` to the corresponding constructor of `value_type`. Return an iterator referring to the newly created and inserted object in this unordered multiset whose value is equivalent to that of an object constructed from `args`. This method requires that the (template parameter) type `KEY` be `emplace‐constructible` into this unordered multiset from `args` (see {Requirements on `KEY`}).
