Insert into this set 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`, if a key equivalent to such a value does not already exists in this set; otherwise, this method has no effect (other than possibly creating a temporary `value_type` object). Return an iterator referring to the (possibly newly created and inserted) object in this set whose value is equivalent to that of an object constructed from `arguments`. The average and worst case complexity of this operation is not affected by the specified `hint`. Note that `hint` is ignored (other than possibly asserting its validity in some build modes).
