I hadn't seen that either - looks like it's new in Python 3.9: https://docs.python.org/3/library/asyncio-task.html#asyncio....

And if you aren't using 3.9, the anyio package has a run_async() function in its to_thread module[1] that works the same way as asyncio's to_thread() coroutine function, and the anyio solution is compatible with both asyncio and trio.
