[Boost-users] [bind] Help with functional composition of shared_ptr::use_count in std::map

Hello all, I'm trying to use bind to help with removeif in a std::map. I want to remove items where the shared_ptr use_count is 1. map Fred; RemoveIf(Fred.begin(), Fred.end(), boost::bind(std::equal_to<long>(), 1, boost::bind(&map

::value_type::second::use_count, _1) )

However, I get a compile error on ::second not being a class or namespace. Anyone know how I should do this? I'm a beginner at boost::bind, so be gentle....
