Here is a simplification of a problem that's been happening in my code:

import contextlib

@contextlib.contextmanager

def f():

    print('1')

    try:

        yield

    finally:

        print('2')

        

g = f()
g.__enter__()

This code prints 1 and then 2, not just 1 like you might expect. This is because when the generator is garbage-collected, it gets `GeneratorExit` sent to it. 

This has been a problem in my code since in some instances, I tell a context manager not to do its `__exit__` function. (I do this by using `ExitStack.pop_all()`. However the `__exit__` is still called here.

I worked around this problem by adding `except GeneratorExit: raise` in my context manager, but that's an ugly solution.

Do you think that something could be done so I won't have to add  `except GeneratorExit: raise` to each context manager to get the desired behavior?

Thanks,

Ram.
