I didn't look at the PR, but from the Subject I bet that
he means that (*iter) returns a constant object, even
for set<Non-Const-Type>::iterator.

If so, then this is not a bug: the elements of set<> have to be
constant, you are not allowed to change them because that would
change the ordering in the set<>.
