If you make this typedef boost::function pf;

public: Bar(pf fn){ fn(true); } };

int main( int argc, char **argv ) {

Bar bar_(foo); // ok.

X x; Bar bar_(boost::bind(&X::f, &x)()); // compile fails.

then Bar bar_( boost::bind(&X::f, &x) ); should work. But you can't get an oridnary function pointer from boost::bind; a function pointer doesn't have enough state to represent &X::f + &x.
