In principle, yes. In PyDia there is a dictionary in the Object interface 
which simplify the access, i.e. can give you all objects properties at once.

The key to use Object::get_props() in C is Object::describe_props() and 
prop_list_from_descs().

Still I'm convinced that using the C interface for prototyping is the wrong 
approach. And I wont provide any sample code there.
