changing this to #include <boost/fusion/include/mpl.hpp> brings in some 
missing stuff to make mpl::begin< fusion::vector<> >::type work

AFAICT insert<> is supposed to work on extensible associative sequences, 
maybe a mpl::vector has been extended to support that concept, but a fusion 
vector might not be.
