OK, that seems to be the source of your confusion, then. This has nothing to do with PEP-416.
We are talking about issue Issue 14417 (like it says in the subject), which in turn is a reaction to the fix for issue 14205.

Don't be so naive, David. This issue is more likely related to immutable dicts whether you like it or not, otherwise there would be no need to patch python 3.3 and include a new dict proxy type without exposing it fully. And secondly this is not only a speculation but my humble understanding of the interdependencies which seems to be related to the inclusion of a new dict proxy (immutable) mapper affecting invariably code expecting a mutable dictionary lookup to succeed whenever the dict structure has changed by (ie) overriding __hash__. Now if you don't mind, I don't mind to remind you how cell phones can be unsafe on an extended period of times for your health and brain so I really don't recommend their uses for cloud-based platforms requiring more advanced thread locking mecanism than what is being included in traditional CPython using standard (mutable) dicts.
