Overview

Select statement is another way to handle multiple channels. It's like switch but each case is a communication.

• All channels are evaluated.
• Blocks until one communication can proceed.
• If multiple can proceed, chooses (pseudo-)randomly.
• A default case, if present, executes immediately if no channel is ready.

Timeout the conversation when no one speaks for 800 ms.
