Nothing special, apparently, at least the line that gets translated 
looks quite innocuous:


     result._doc = etree

where result is an extension type instance defined by Pyrex with _doc 
defined as a C-level element, and etree is another extension type instance

the translation is something like this:

   ((PyObject *)__pyx_v_result->__pyx_base._doc) = ((PyObject 
*)__pyx_v_etree);

If I understand correctly, to make this work we'd need to change the 
code generation so it doesn't generate the cast on the left hand side. 
The right hand side is already casting correctly.
