You should take a look at AnyIO, which unifies asyncio and Trio (it can use both event loops as a backend).

Two big deals of Trio and AnyIO are channels (similar to Go's channels), the ability to return data from starting a task in a nursery/task group:

    async def my_consumer(task_status = anyio.TASK_STATUS_IGNORED):
        tx, rx = anyio.create_memory_object_stream()
        task_status.started(tx)

        async for message in rx:
            ...

    async def my_producer(tx):
        await tx.send("hello")
        await tx.send("world")
        await tx.aclose()

    async def main():
        async with anyio.create_task_group() as tg:
            tx = await tg.start(my_consumer)
            tg.start_soon(my_producer, tx)
