First time using channels

channels.go

func execute(cmd *Cmd, conn ircConnection) {
	done := make(chan bool, len(list))

	for k, v := range list {
		cmdName := k
		cmdFunc := v
		go func() {
			result := cmdFunc(cmd)
			conn.Privmsg(cmd.Channel, result)
			done <- true
		}()
	}

	for _, _ = range passiveCommands {
		<-done
	}
}
