Right now, I can't think of a way yet of how to do this. But the
intention here is to be able to do this:

transform(my_map.begin(), my_map.end(),
  boost::make_function_output_iterator(my_function),
  boost::select<0>());

This will take the first argument of the pair contained in the map and
feed it into 'my_function'.

I hope this makes sense.
