Re: [Boost-users] [Boost.Range] Filtering elements at even position

I am trying to create a range consisting of elements in a container at only even indexes. Is there a way to write something like:

vec | boost::adaptors::indexed(0) | some_adaptor_to_choose_even_indexes

I tried with boost::adaptors::filtered, but the index information is only present in iterators of the generated range, not in its value_type so it is not available in chained adaptors.
