.. versionadded:: 3.7

:func:`asynccontextmanager` uses :class:`AsyncContextDecorator` so the context managers
it creates can be used as decorators as well as in :keyword:`async with` statements.
When used as a decorator, a new generator instance is implicitly created on
each function call (this allows the otherwise "one-shot" context managers
created by :func:`asynccontextmanager` to meet the requirement that context
managers support multiple invocations in order to be used as decorators).

.. versionchanged:: 3.10
Use of :class:`AsyncContextDecorator`.
