Yes. If you give an extension type a __next__ method, it
will get called in response to next(). Also, you can give
your collection class an __iter__ method just as in
Python.

If you write 'class MyClass' in Pyrex, you get an ordinary
Python class. Since that's the more Python-like behaviour,
it gets the more Python-like syntax.

The difference between 'def' and 'cdef' for functions is
that 'def' functions can be called from Python, whereas
'cdef' ones can't. Again, the more Python-like one gets
Python syntax.
