If I'm iterating over a map with, say find_if, and my predicate function accepts the mapped_type of the map, is there a mechanism to pick out the pair.second value inline?

class C;

map< int, C > m;

bool pred( const C & );

// correct version of this intent. find_if( m.begin( ), m.end( ), pred( second ) );

find_if(m.begin(), m.end(), bind(pred, bind(&map::value_type::second, _1)))

Many thanks Roman - I find these bind incantations a bit like grasping at smoke, one week I get familiar with it all, and the next week the syntax just slips away! - Rob.
