It's easy to go, but how to stop?

Long-lived programs need to clean up.

Let's look at how to write programs that handle communication, periodic events, and cancellation.

The core is Go's select statement: like a switch, but the decision is made based on the ability to communicate.

case y := <-yc:
    // received y from yc
}
