    "For" loops may now range over integers.
    For <a href="https://go.dev/play/p/ky02zZxgk_r?v=gotip">example</a>:
<pre>
package main

import "fmt"

func main() {
  for i := range 10 {
    fmt.Println(10 - i)
  }
  fmt.Println("go1.22 has lift-off!")
}
</pre>
    See the spec for <a href="/ref/spec#For_range">details</a>.
  </li>
</ul>

goroutines coordinate using the <code>limit</code> channel to ensure
that at most three are running work functions at a time.
</p>

<pre>
var limit = make(chan int, 3)

func main() {
	for _, w := range work {
		go func(w func()) {
			limit &lt;- 1
			w()
			&lt;-limit
		}(w)
	}
	select{}
}
</pre>
