Actually, this is too naive an implementation as iterator_range<> lacks

There is one more annoyance, I think. std::pair<T,U> lacks a 
operator<<() which means the following will fail:

BOOST_CHECK_EQUAL_RANGE( ba::map_list_of("foo",1)("bar",2), get_map() );

Is it reasonable that operator<<() is required when we simply want to
test comparison with ==? Perhaps there should be a way to get rid of 
that requirement?

That is quite ok. Just include everything in that header then.
