New submission from Daniel Pope :
The anext_awaitable object returned by anext(..., default) does not support
.send()/.throw(). It only supports __next__().
So we can pass messages from the suspending coroutine to the event loop but not

A tarfile.TarFile object open for writing may silently write corrupt tar files

While explicitly calling close() or using the object as a context manager is
recommended, I would not expect this in basic usage.

This would be a shortcut in the common case that you simply want an idempotent
"make sure this file/symlink is gone" operation.
