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.

typedef boost::variant< int, std::string, short, long > type_list;
| <boost/variant.html>|
Is it possible to create a variant from a sequence by either passing the 
sequence or iterating through each value in the sequence?  This would 
reduce the code duplication of having one sequence for assert checking 
and the other for variants.
