-'''
-This module provides a newnext() function in Python 2 that mimics the
-behaviour of ``next()`` in Python 3, falling back to Python 2's behaviour for
-compatibility if this fails.
-
-``newnext(iterator)`` calls the iterator's ``__next__()`` method if it exists. If this
-doesn't exist, it falls back to calling a ``next()`` method.
-
-For example:
-
-    >>> class Odds(object):
-    ...     def __init__(self, start=1):
-    ...         self.value = start - 2
-    ...     def __next__(self):                 # note the Py3 interface
-    ...         self.value += 2
-    ...         return self.value
-    ...     def __iter__(self):
-    ...         return self
-    ...
-    >>> iterator = Odds()
-    >>> next(iterator)
-    1
-    >>> next(iterator)
-    3
-
-If you are defining your own custom iterator class as above, it is preferable
-to explicitly decorate the class with the @implements_iterator decorator from
-``future.utils`` as follows:
-
-    >>> @implements_iterator
-    ... class Odds(object):
-    ...     # etc
-    ...     pass
-
-This next() function is primarily for consuming iterators defined in Python 3
-code elsewhere that we would like to run on Python 2 or 3.
