[Cython] __next__ | not being able to use cpdef

[Jelle Feringa]

Right, but this isn't any different from looping through a vanilla  
python iterable, right?
Simply typing the number that indexes the iterable already loops twice  
as fast, although obviously its rather trivial code.
Actually, it would be interesting to see if a fast __getitem__ call  
would be available, since that would facilitate writing fast  
specialized iterators easily.
