Go by Example: Range over Channels

In a previous example we saw how `for` and `range` provide iteration over basic data structures. We can also use this syntax to iterate over values received from a channel.
	package main
	import "fmt"
	func main() {
We’ll iterate over 2 values in the `queue` channel.	queue := make(chan string, 2) queue <- "one" queue <- "two" close(queue)
This `range` iterates over each element as it’s received from `queue`. Because we `close`d the channel above, the iteration terminates after receiving the 2 elements. If we didn’t `close` it we’d block on a 3rd receive in the loop.	for elem := range queue { fmt.Println(elem) } }

	$ go run range-over-channels.go one two
This example also showed that it’s possible to close a non-empty channel but still have the remaining values be received.
