I think it totally makes sense to adapt some components of the STL. Constexpr
containers like `std::array`, `std::tuple` and `std::integer_sequence` are
straightforward, but runtime-only containers like `std::vector` are giving
me problems right now. I'm searching for a solution. See [1] for an example
of using `std::array`.

Thanks for the heads up. Is there a link to that code, or is it already
in the Boost distribution? I did find a C++11 implementation of fusion::map
in fusion/container/map/detail/map_impl.hpp, but is that all?
