Hi all,

I am unexpectedly stuck looking for some functionality which I assumed
would be present.  Given an MPL sequence, I want to generate the type
of a corresponding fusion sequence, which I can then use to store
things:

mpl::vector<int, string> mpl_vec;
typedef some_metafunction<mpl_vec>::type fusion_vec; // equivalent to
fusion::vector<int, string>
fusion_vec vec(5, "foo");

Does some_metafunction exist?  I'm not sure if I'm just not seeing it
(or perhaps thinking wrongly about the problem), or if it really is
not present.

I was looking at the fusion/mpl bridge at [1], but its functionality
seems orthogonal to what I want.

Thanks,
-Gabe
