<p>
  As mentioned in the <a href="/doc/go1.20#bootstrap">Go 1.20 release notes</a>, Go 1.22 now requires
  the final point release of Go 1.20 or later for bootstrap.
  We expect that Go 1.24 will require the final point release of Go 1.22 or later for bootstrap.

var a string

func f() {
	print(a)
}

func hello() {
	a = "hello, world"
	go f()
}

<p>
calling <code>hello</code> will print <code>"hello, world"</code>
at some point in the future (perhaps after <code>hello</code> has returned).
