My attempt however fails when trying to use the metafunction tuple_of_references::type for the std::tuple of iterators. This is what I tried (https://godbolt.org/z/Ymjtvn):

zip_iterator works with fusion sequences.
Make sure you include boost/fusion/adapted/std_tuple.hpp

Also std::get<N>(x), not x.get<N>().
