[issue42837] Symbol table incorrectly identifies code as a generator, when 'yield' occurs in an annotation

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

The aim is to change the behavior of the symbol table to match the compiler.
The behavior has already changed at module scope.

Python 3.9.0+
>>> x:(yield None)
  File "<stdin>", line 1
SyntaxError: 'yield' outside function
>>> 


Python 3.10.0a4+
>>> x:(yield None)
>>>
