[Boost-users] [Range & c++0x Lambdas] Can this be done?

Can the last line, labelled NOT Ok, be made to work? I think the lambda does not publish its result as a bind does, so I suspect it's hopeless. Any thoughts? Thx, Rob. #include #include #include #include <vector> #include <algorithm> struct S { int i; }; void f( std::vector<int> & out, std::vector<S> & in ) { using boost::adaptors::transformed; // Ok std::transform( in.begin( ), in.end( ), std::back_inserter( out ), bind( & S::i, _1 ) ); // Ok boost::range::push_back( out, in | transformed( bind( & S::i, _1 ) ) ); // Ok std::transform( in.begin( ), in.end( ), std::back_inserter( out ), []( S & s ) { return s.i; } ); // NOT Ok boost::range::push_back( out, in | transformed( []( S & s ) { return s.i; } ) ); }
