For a channel <code>c</code>, the built-in function <code>close(c)</code>
records that no more values will be sent on the channel.
It is an error if <code>c</code> is a receive-only channel.
Sending to or closing a closed channel causes a <a href="#Run_time_panics">run-time panic</a>.
Closing the nil channel also causes a <a href="#Run_time_panics">run-time panic</a>.
