Let's see a few variants (continuing the same example)

#include <boost/range/algorithm/copy.hpp>
#include <boost/assign/v2/include/do_csv_put.hpp>
#include <boost/assign/v2/include/csv_deque_ext.hpp>
#include <iostream>
#include <iterator>

// Variant #2
{   // Boost.Assign 2.0
     using namespace boost::assign::v2;
     map_ map;
     boost::copy(
         map | do_csv_put<2>( "jan", 31, "feb", 28, "mar", 31 )
             | boost::adaptors::map_keys,
             std::ostream_iterator<str_>( std::cout, " ")
     ); // prints feb jan mar
}

// Variant #3
{   // Boost.Assign 2.0
     using namespace boost::assign::v2;
     map_ map = converter(
          csv_deque<p_, 2>( "jan", 31, "feb", 28, "mar", 31 )
     );
}

PS:
- csv_deque<p_, I>( a1,...aI, ..., z1,...,zI ) is same as
deque<p_>( a1, ..., aI)...(z1, ..., zI)
- deque's nearest equivalent in Boost.Assign ( 1.0 ) is list_of
- do_csv_put<>() is C++0x only as of current revision

Any questions?
