Thanks, would be great. Anyway, In the source of boost.python I saw a 
lot of used detail::.. stuff. The raw:pyobject header says this are to 
hide to the user. What are the correspondent user functions for
new_reference, borrowed_reference and new_non_null_reference which are 
more in common sense of the python C/API documentation.

Thanks,
Olaf
