I noticed that fusion_v2 uses some sort of boost_pp to forward args:

and something similar is done for vector and maybe elsewhere in
fusion.  Does anyone plan to generalize these forwarding generator's
so that they can be used in fusion_v2 ( and eventually as an
alternative to the one's in http://tinyurl.com/o7zlg )?
