The private/public distinction in Cython is not as in C++, it is just
related to exposing C/C++ stuff to Python land... Inside a module
coded in Cython, everything is (in the C++ sense) public .
Yur do_something_on_Polygon() is missing a "cast", or Cython does not
know that someting is actually a cdef class.
def do_something_on_Polygon(self,Rectangle_list):
cdef Rectangle r = Rectangle_list[0]
self.thisptr.do_something(r.thisptr)
