Hello Following my previous post, the transformed iterator has input iterator tag (not forward, not bidir, not random) BOOST_STATIC_ASSERT(( boost::is_convertible< iteratorIntoFirst, std::input_iterator_tag

...

::value ));

But it should be random_access... Is there anything extra I need to put in the Unary fct of transform_iterator? Rds,

There seems to be some boost::random_access_traversal_tag, and the static assert works with this tag??? Why isn't boost::random_access_traversal_tag equivalent to std::random_access_iterator_tag ? Rds,
