Steven and I were playing with different syntaxes few years ago

We came up with something like this:

    void BOOST_LOCAL_FUNCTION
        ( BOOST_BIND((factor)(&sum)), double num )
    {
        sum += factor * num;
        std::clog<<  "Summed: "<<  sum<<  std::endl;
    }
    BOOST_LOCAL_FUNCTION_DECL(add)
