FWIW, oven(http://tinyurl.com/2axp2l) implemented that. :-)

BOOST_FOREACH (string v, make_map_values(m)) {
   // ...
}

make_map_values(m) is synonym of make_elements<mpl::int_<1> >(m)
that iterates over a range of FusionSequence.

I agree no specific iterator is needed.
make_elements is actually implemented using transform_iterator and a FunctionObject.

Also note that Boost.Lambda can't be used here.
A Boost.Lambda functor is not Assignable.
