The reason I returned to my post is that today I found boost/mpl/
plus.hpp and boost/mpl/multiplies.hpp which seem to answer the first
part of my question (although not the syntactic sugar part).
mpl::plus and mpl::multiplies are not function objects.  You
can't use them with int, for example.  They are metafunctions
that mainly work with MPL Integral Constant Wrappers:

BOOST_MPL_ASSERT((boost::mpl::equal_to<
  boost::mpl::plus, boost::mpl::int_<2> >,
  boost::mpl::int_<3> >));
