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

<h3 id="goexit">Goroutine destruction</h3>

<p>
The exit of a goroutine is not guaranteed to be synchronized before
any event in the program.
For example, in this program:
</p>

<pre>
var a string

func hello() {

            return true;
        }

        if (!(other instanceof Restriction)) {
            return false;
        }

        Restriction restriction = (Restriction) other;
        if (lowerBound != null) {
            if (!lowerBound.equals(restriction.lowerBound)) {
                return false;
            }
        } else if (restriction.lowerBound != null) {
            return false;
        }
