You might want to look at the Boost.Fusion library 
(http://www.boost.org/doc/libs/1_64_0/libs/fusion/doc/html/).

Or if this is C++11+ code, at std::tuple and std::get.  Though some of 
these might still require values known at compile time; depending on 
your usage you might be able to use constexpr methods for that, however.
