Comment(by anonymous):

 The previous comment referring to assoc_item was from:

 [https://sourceforge.net/tracker/?func=detail&atid=207586&aid=1642614&group_id=7586]

 The recent assoc_by_insert.cpp attachment shows simpler solution which
 folds over the set insert operation instead of the set s_item operation
 in the superclass of set<T1,T2,...,Tn>
 The reason it works is because the fold starts from the empty set, which
 has no duplicates, and the insert operation preserves the no duplicate
 invariant.
