-.. function:: set_coroutine_wrapper(wrapper)
-
-   Allows intercepting creation of :term:`coroutine` objects (only ones that
-   are created by an :keyword:`async def` function; generators decorated with
-   :func:`types.coroutine` or :func:`asyncio.coroutine` will not be
-   intercepted).
-
-   The *wrapper* argument must be either:
-
-   * a callable that accepts one argument (a coroutine object);
-   * ``None``, to reset the wrapper.
-
-   If called twice, the new wrapper replaces the previous one.  The function
-   is thread-specific.
-
-   The *wrapper* callable cannot define new coroutines directly or indirectly::
-
-        def wrapper(coro):
-            async def wrap(coro):
-                return await coro
