Breaking the concrete proposal out to its own post: - for CPython, "nonlocal __class__" becomes a SyntaxError generated by the symbol table pass in the compiler in 3.7+ and a DeprecationWarning in 3.6.1+ - other implementations (including PyPy) can just make "nonlocal __class__" a SyntaxError immediately - an explicit test be added to https://hg.python.org/cpython/file/default/Lib/test/test_super.py for 3.6+ that "__class__" and "__classcell__" don't show up in the class locals() during execution of the class body
