A new PEP for Python 3.11 proposes to introduce a new special form called Self exported from the typing module.

Pyright already implements this in an implicit manner, inferring the type of self and cls parameters when they are unannotated, so it should be easy to prototype this new functionality.

This is addressed in pyright 1.1.184, which I just published. It will also be included in the next release of pylance.

pyright & corelib: reduce dependence on type inference (Self type)
cea8200 
For library codes, Pyright' type inference does not work properly. This commit addresses the issue. If typing.Self is implemented in the future, we could handle such cases in an easier way.
