BTW, is this true also for N3351 concepts or just for C++0x concepts?
Because iterator tags are still in N3351 and they are even made part
of the specification (so they're not just an implementation

concept InputIterator<WeakInputIterator I> =
    EqualityComparable<I> &&
    Derived<IteratorCategory<I>, input_iterator_tag>;
