Running mypy against this code:

import aiofiles
# ...
async with aiofiles.open('filename', 'wb') as file:
    # ...

returns these errors:

error: "AsyncBufferedIOBase" has no attribute "__aenter__"
error: "AsyncBufferedIOBase" has no attribute "__aexit__"

I'm using:

Python 3.8.6
aiofiles          0.6.0
mypy              0.790

Upgrading to v0.812 should resolve the issue

See: python/mypy#9739
