Would this work?

Well, the example I gave was probably overly simple. The real example uses
a boost::python::list, which can either take a char* or a std::string. At
the time I'm doing the boost::bind, I do not know what type is being passed
in.
Below is the real example:

//=========================================================================================
bool PyInterpreter::SetSystemPath( std::vectorboost::filesystem::path
const& pathList )
{
    bool success = true;

    try
    {
        using namespace boost::python;

        list newsyspath;

        std::for_each( pathList.begin(), pathList.end(), boost::bind(
&list::insertboost::filesystem::path, newsyspath, 0, _1 ) );

        object sys = GetNamespace( "sys" );
        sys["path"] = newsyspath;
    }

    catch(...)
    {
        PyErr_Print();
        success = false;
        assert( 0 );
    }

    return false;
}

If you examine my std::for_each() above, you'll notice that I'm simply
trying to push 'path' objects into boost::python::list, which won't work but
it should at least compile. However the MSVC compiler is telling me that
boost::bind expects 2 arguments, not 4. What am I doing wrong?
