I have a sequence of types defined with the Loki library. I believe the equivalent would be boost::mpl::vector. The sequence is used to cause compile time asserts for unsupported types being passed to template functions. Boost variant can be created with a given list of types.

I doubt Boost.Variant is the best choice for this. You say a template function to enforce types, I would say Boost.Enable_if combined with Boost.Type_traits and Boost.MPL would make it real easy.
