 //! This module provides message-based communication over channels, concretely

-//! * `Sender`
-//! * `SyncSender`

 //! senders are clone-able (multi-producer) such that many threads can send
 //! simultaneously to one receiver (single-consumer).

 //! These channels come in two flavors:
 //!

 //!
-//! 2. A synchronous, bounded channel. The `sync_channel()` function will return
