yes, this worked, but next, more simple example not work:

std::map <int, std::string> m;
std::vector <int> v;

std::transform( m.begin(), m.end(), std::backinserter(v),
bind(&std::pair<const int, std::string>::second, _1) );

even replacing 'bind' by _1 ->* &std::pair<const
int,std::string>::second doesn't work.
GCC 4.1.2 reports:
error: reference to '_1' is ambiguous
/usr/include/boost/lambda/core.hpp:69: error: candidates are: const
