- What's this?
add_listener(channel_name, listener_key=NOTHING)
public
Adds the passed proc as a listener on the channel indicated by channel_name. listener_key is used to remove the listener later; if none is specified, the proc itself is used.
Whatever is used as the listener_key is returned, making it very easy to use the proc itself as the listener_key:
listener = add_listener("Channel") { ... } remove_listener("Channel", listener)
