frozendict_builtins.patch: make CPython supports frozendict for the __builtins__ mapping. It is an example of frozendict usage which helps my pysandbox project.

Another frozendict usage example: freeze the dict of a new type if it contains __final__ in its namespace. Example: >>> class Classic: ... pass ... >>> Classic.attr=1 >>> class FinalizedType: ... __final__=True ... >>> FinalizedType.attr=1 (...) TypeError: 'frozendict' object does not support item assignment This patch is not part of the PEP 416 and is just a proof-of-concept.

The PEP has been rejected. See issue #14386 for a new mappingview type.
