Its close but not quite. I get an error message that _1 is ambiguous
Append_Frame.cpp:48: error: reference to '_1' is ambiguous
/usr/include/boost/lambda/core.hpp:69: error: candidates are: const boost::lambda::placeholder1_type& boost::lambda::<unnamed>::_1
/usr/include/boost/bind/placeholders.hpp:54: error: boost::arg<1> <unnamed>::_1
