Here I'm also retargeting this to Python 3.10 and proposing various
small changes to clarify the PEP. In addition, we have a new reference
implementation in the works.
* Add PEP-0604 to describes an extension to Python language, which aims to add a complementary
syntax to write ``Union[X,Y]`` and ``Optional[X]`` easier.
* Add sample with metaclass with __invert__ and/or __or__
* Remove operator __revert__
* Change title of pep-604
