[boost] [variant, MPL] Is there a variant -> mpl sequence metafunction ?

make_variant_over<Seq>::type

creates a variant type from an MPL Sequence.

Is there an operation that would do the opposite, create an MPL 
sequence from a variant?

I cannot just use the type parameter list as such because the types 
that stand for an empty
type are different in both libraries: boost::detail::variant::void_ in 
variant, and something
else in MPL.

  Best, Jaakko
