PEP 479: Change StopIteration handling inside generators
--------------------------------------------------------
:pep:`479` changes the behavior of generators: when a :exc:`StopIteration`
exception is raised inside a generator, it is replaced with a
:exc:`RuntimeError`. To enable the feature a ``__future__`` import should
be used::
from __future__ import generator_stop
Without a ``__future__`` import, a :exc:`PendingDeprecationWarning` will be
raised.
PEP written by Chris Angelico and Guido van Rossum. Implemented by
Chris Angelico, Yury Selivanov and Nick Coghlan.
