Comment(by Jeffrey Hellrung <jhellrung@…>):

 Okay, I'll try my hand at it.  Could be a week or two, though ;)

 Also, there's another Fusion addition I use that I've found useful:
 as_mpl_vector.  It is strictly a metafunction which converts a
 Boost.Fusion conforming sequence into a Boost.MPL vector.  I know all
 "built-in" Fusion sequences are already MPL sequences (with the
 appropriate include), but it didn't seem like adapted Fusion sequences
 also had this property, hence the need arose.  I've occasionally needed
 this to add compile-time checks or type-computations on a Boost.Fusion
 parameter to a function.  Let me know if this also sounds like something
 that could be added, or if you need an example use case.
