[intrusive.set] Accessing the last (largest) element.
Since there is no "back" method for intrusive set, what's the best way to access the last (greatest) element? Is this OK:? IntrusiveSet set1; IntrusiveSet::iterator itEnd = set1.end(); //Make sure that set isn't empty. Value v = *--itEnd; ++itEnd; //will itEnd point to set1.end() after this? In general, is there anything sinister about this construct? (provided that the set isn't empty) Thanks, Andy.

Yes, what about rbegin()?
Yup, rbegin will work. But I already have a range (begin<-->end), and just need to access the last element in the range.
Best,
