I think it should be PyType of Object, (PyObject *)Object_Type

for this to work we need to provide a /* initproc tp_init; */ for each 
type and then add constants to its dictionary.


This means you can do

ObType = type(bpy.data.objects['Cube'])
new_ob = ObType()

We could enforce arguments also - like object data or the scene for instance

(I think object data is a must, scene could default to the current scene)

Some types should raise an NotYetImplimented error on initialization - 
like sounds and fonts.
