+    Async counterpart to :func:`antiflood`. Awaits ``function(*args, **kwargs)``
+    in a retry loop that honours Telegram's ``retry_after`` parameter on 429

+
+    .. code-block:: python3

+
+        for chat_id in chat_id_list:

+        attempt, so pass the function itself (for example ``bot.send_message``),
+        not a pre-awaited coroutine.
+    :type function: :obj:`Callable`
+
+    :param number_retries: Total number of attempts. After ``number_retries - 1``
+        retried 429 responses the final call is issued without the 429 guard,
+        so its exception will propagate.
+    :type number_retries: :obj:`int`
+
+    :param args: Positional arguments forwarded to ``function``.
+    :param kwargs: Keyword arguments forwarded to ``function``.
+
+    :return: Whatever ``function`` returns on the first successful call.
