Making your own header file and defining `foreach` macro in the header
might be a better solution:

    // my_foreach.h
    #include <boost/foreach.hpp>

    #include <boost/multi_index_container.hpp>
    #include <boost/multi_index/hashed_index.hpp>
    #include <boost/multi_index/ordered_index.hpp>
    #include <boost/multi_index/random_access_index.hpp>
    #include <boost/multi_index/sequenced_index.hpp>

    #define foreach BOOST_FOREACH

Then, whenever you use `foreach`, include this header file.
By doing so, you don't have to worry about the ordering of
header files and the macro definition.
