Support python 3.11

[ayalash]

All unittests fails when running with python 3.11 on ValueError:

ValueError: AST node line range (7, 1) is not valid

(some tests fails on range (12,1)).

It might be related to: python/cpython#93351

I really want to upgrade to 3.11 for my slash tests that depend on this. Let me know if I can help here.
