[Feature Request] let ActionCable to broadcast to every but yourself

[udry]

We have a method like this:

ActionCable.server.broadcast "some_channel", message: "blah-blah"

But in this way the message will be sent to all the subscribed users, including the current user.

Can't we have one like

ActionCable.server.broadcast_to_others(channel, body)

which broadcasts to everybody but himself, or

ActionCable.server.broadcast_except(subscriber, channel, body)

or some method?

I've tried to look at the source, but ActionCable holds the subscribers as an Array so i was hard to work with it..

thanks,
