How can I print to Stderr in Go without using log

How can I write a message to Stderr without using log?

A comment in this SO post shows how to do it with log: log.Println("Message"), but what if I don't want a timestamp?

Is the following good Go?

os.Stderr.WriteString("Message")

If you don't want timestamps, just create a new log.Logger with flag set to 0:

l := log.New(os.Stderr, "", 0)
l.Println("log msg")

EDIT:

Is the following good Go?
os.Stderr.WriteString("Message")

This is acceptable, and you can also use fmt.Fprintf and friends to get formatted output:

fmt.Fprintf(os.Stderr, "number of foo: %d", nFoo)

Using the fmt package, you can choose to write to stderr this way:

import "fmt"
import "os"

func main() {
    fmt.Fprintln(os.Stderr, "hello world")
}

The Go builtin functions print and println print to stderr. So if you simply want to output some text to stderr you can do

package main

func main() {
    println("Hello stderr!")
}
