Submission for SC consideration: PEP 673 -- Self Type

[pradeep90]

Please consider PEP 673 for inclusion in Python 3.11. This is primarily of interest to users of static type checkers. It provides a simple and intuitive way to annotate methods that accept or return an instance of their class.

The PEP has been discussed at length in typing sig and on the draft doc. We have also notified python-dev.

There are reference implementations of the type checking part in Pyright and Mypy. There is also an implementation of the Self special form in typing_extensions.py.
