The problem I see with both a tuple_vector and a vector of 
boost::variant's is that the types that can be added to the containers 
are part of the declaration of the container, so you have to know them 
in advance. When this is possible IMO you approach is good. Density is 
addressing the case in which the declaration of the container can't 
depend on the type of elements. Think to the dense_function_queue. An 
element of this container may be the result of an std::bind, or a 
lambda, which are unnamed types.
