Arguments on callback functions?

[TheFern2]

Good day, I am a bit new to golang, how do you do a callback function where you need to pass an argument other than the message? I am having issues adding the callback to the SubscriberConf

func OnSignalArrayMessage(msg *msg.SignalArray, someBool bool) {
	for _, m := range msg.Data {
		fmt.Printf("%v\n", m)
	}
}

solution is here #42

Ah anonymous funcs, nice. Dunno how I missed that one during my search.
