Could you provide some benchmarks justifying use of fusion tuple
vs. indexed_types/composite_product.hpp.  I know David provided some
reasons in:

   http://article.gmane.org/gmane.comp.lib.boost.devel/115108

however, no benchmarks were provided and no "detailed" justifcation
explaining why it would be better than composite_product.  Indeed, it
would be impossible at that time since apparently the
composite_product code hadn't been looked at, according to this quote:

   I guess you're assuming I've looked at your code again ;-)

from:

   http://article.gmane.org/gmane.comp.lib.boost.devel/115530

I'd be happy to help with coding and running benchmarks.
