Assign to this object the value resulting from first clearing this set and then inserting each `value_type` object in the specified `values` initializer list, ignoring those keys having a value equivalent to that which appears earlier in the list; return a reference providing modifiable access to this object. This method requires that the (template parameter) type `KEY` be `copy‐insertable` into this set (see {Requirements on `KEY`}).
