Yes, it does affect the local control flow. If you don't assign the return value, then the local actor will proceed execution of the next thing, so effectively async execution of the remote method call. You can also write this explicitly like so:

    async remote_actor.foobar()

If you on the other hand want to wait for that remote actor to finish but still not assign locally you can use a dummy variable:

    _ = remote_actor.foobar()

or explicitly ask to await

    await async remote_actor.foobar()

You can also explicitly ask for async while grabbing the return value, which makes it easy to run things concurrently

    a1 = async remote_actor1.foobar()
    a2 = async remote_actor2.foobar()
    print("a1 and a2 run concurrently")
    r1 = await a1 # collect both results
    r2 = await a2
    print(r1, r2)
