You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: chan5.go
    path of file: ./repos/yaegi/_test
    
    the code of the file until where you have to start completion: package main

import "time"

func main() {

	// For our example we'll select across two channels.
	c1 := make(chan string)
	c2 := make(chan string)

	// Each channel will receive a value after some amount
	// of time, to simulate e.g. blocking RPC operations
	// executing in concurrent goroutines.
	go func() {
		//time.Sleep(1 * time.Second)
		time.Sleep(1e9)
		c1 <- "one"
	}()
	go func() {
		time.Sl
    
func main() {

	// For our example we'll select across two channels.
	c1 := make(chan string)
	c2 := make(chan string)

	// Each channel will receive a value after some amount
	// of time, to simulate e.g. blocking RPC operations
	// executing in concurrent goroutines.
	go func() {
		//time.Sleep(1 * time.Second)
		time.Sleep(1e9)
		c1 <- "one"
	}()
	go func() {
		time.Sleep(2e9)
		c2 <- "two"
	}()

	msg1 := <-c1
	println(msg1)

	msg2 := <-c2
	println(msg2)
}
