	// This is the nice and succinct way to read one item each from a set of channels,
	// which I like:
	a, b, c := <-ch1, <-ch2, <-ch3
	fmt.Println(a, b, c)

	// And, to demonstrate that the order in which we receive items is not important, we are
	// receiving in the reverse order compared with the order in which they were sent,
	// which works because of bufSize >= 1:
	c, b, a = <-ch3, <-ch2, <-ch1
	fmt.Println(a, b, c)
