Inside a <code>select</code>, that property removes the associated communication case from the set of cases eligible to run, without requiring a separate condition around the <code>select</code>.</p> <p>This behavior follows directly from the channel contract. The zero value of a channel is <code>nil</code>, and a nil channel is never ready for communication. A standalone send or receive therefore blocks indefinitely. A <code>select</code> treats the same operation as a case that cannot currently proceed.</p>
