Bug report

Bug description:

Prior to Python 3.12, we can close a just created coroutine, thus, the following test passes:

frominspectimportgetcoroutinestate,CORO_CLOSEDasyncdefdo_nothing():passdeftest_immediate_close():coro=do_nothing()coro.close()assertgetcoroutinestate(coro)==CORO_CLOSED

But in Python 3.12, the assertion fails andgetcoroutinestate(coro) still isCORO_CREATED after thecoro.close(). You can confirm it fromhttps://github.com/gottadiveintopython/py312/actions/runs/6571303025/job/17850194150.

I don't know if this is an intensional change or not, but I just wanted to tell you.

CPython versions tested on:

3.12

Operating systems tested on:

Linux
