Hi Jeremy and/or anyone else who cares,
I am thinking that the iterator adaptor library is overly enthusiastic in
selecting the operator_arror_proxy for the result of its operator->()
whenever the iterator is no more refined than InputIterator. Shouldn't we
also ask whether the associated reference type is not a reference before we
resort to the proxy? That would be more efficient for lots of cases, and
would even enable operator->() when iterator_adaptor is used to iterate over
an abstract class.
Have I missed something?
