It is a bit of a pain to have to resort to the typedef. Because I iterate over std::maps quite a lot, I've semi-seriously toyed with the idea of a submitting a feature request for
BOOST_FOREACH_PAIR( std::pair<T1,T2> const& my_pair , my_container_with_a_pair_value_type )
which through a bit of PP_CAT and PP_COMMA somehow does the "right" thing. Given the potential for confusion though, I assumed Eric would reject the request :-).
