li,chen 44b5f310c5 use function next() instead of next() method on iterator objects
Python 3 introduced a next() function to replace the next() method on
iterator objects. Rather than calling the method on the iterator, the next()
function is called with the iterable object as it's sole parameter, which
calls the underlying __next__() method.

The next() function was backported to Python 2.6 which allows us to use either
the 2.x or 3.x way simultaneously.
