The take-away for this discussion is that forward iterator and any of its refinements like bidirectional iterator and random access iterator have to return a reference in operator*.
Just curious, do you have any idea what standard library implementations at present actually rely on this? Was this addressed at all in C++0x? I.e., were the iterator concepts formally "orthogonalized" to separate access concepts from traversal concepts, as outlined in the Boost.Iterator library? 'Cause disallowing proxy references on random access traversal and bidirectional traversal iterators...that sucks. Sorry to change the topic... :/ - Jeff
