Functional options: https://gist.github.com/travisjeffery/8265ca411735f638db80e2e34bdbd3ae

In real world we need to validate input. This functional options kills global namespace. Take a look my average config:

import (
   "domain.tld/user/log"
)

// default configs

// in this example the Event is an event, that requires updates in our Root
func startHandlingSomePack(events <-chan Event, pack *skyobject.Pack,
	n *node.Node, wg *sync.WaitGroup) {

	go handleSomePack(n, pack, events, n.Quiting(), wg)
}

func handleSomePack(n *node.Node, pack *cxo.Pack, events <-chan Event,
	quit <-chan struct{}, wg *sync.WaitGroup) {
