How can I pretty-print JSON using Go?

Question

Does anyone know of a simple way to pretty-print JSON output in Go?

The stock http://golang.org/pkg/encoding/json/ package does not seem to include functiona

For better memory usage, I guess this is better:

var out io.Writer
enc := json.NewEncoder(out)
enc.SetIndent("", "    ")
if err := enc.Encode(data); err != nil {
    panic(err)
}
