@Fidget-Spinner Do you have time to review? |

FWIW the CI failure seems unrelated, it's homebrew being difficult (see #build channel on Discord). |
In some cases we might cause a StreamWriter to stay alive even when the application has dropped all references to it. This prevents us from doing automatical cleanup, and complaining that the StreamWriter wasn't properly closed. Fortunately, the extra reference was never actually used for anything so we can just drop it.
…hon#115667) Nothing else in Python generally logs the contents of variables, so this can be very unexpected for developers and could leak sensitive information in to terminals and log files.
Demonstration:
>>> ast.FunctionDef.__annotations__
{'name': <class 'str'>, 'args': <class 'ast.arguments'>, 'body': list[ast.stmt], 'decorator_list': list[ast.expr], 'returns': ast.expr | None, 'type_comment': str | None, 'type_params': list[ast.type_param]}
>>> ast.FunctionDef()
<stdin>:1: DeprecationWarning: FunctionDef.__init__ missing 1 required positional argument: 'name'. This will become an error in Python 3.15.
<stdin>:1: DeprecationWarning: FunctionDef.__init__ missing 1 required positional argument: 'args'. This will become an error in Python 3.15.
<ast.FunctionDef object at 0x101959460>
>>> node = ast.FunctionDef(name="foo", args=ast.arguments())
>>> node.decorator_list
[]
>>> ast.FunctionDef(whatever="you want", name="x", args=ast.arguments())
<stdin>:1: DeprecationWarning: FunctionDef.__init__ got an unexpected keyword argument 'whatever'. Support for arbitrary keyword arguments is deprecated and will be removed in Python 3.15.
