[FeatureRequest] F2 rename a function or class, should result changes in __all__

[loynoir]

Actual

Change def <F2>pre</F2>(): to def post():

__all__ = ['pre']

def pre():
    pass

Error: Undefined variable name 'pre' in __all__

__all__ = ['pre']

def post():
    pass

Expected

Change def <F2>pre</F2>(): to def post():

__all__ = ['pre']

def pre():
    pass

__all__ = ['post']

def post():
    pass
