The documentation for objects.Download states:

Download is a function that retrieves the content and metadata for an object. To extract just the content, pass the DownloadResult response to the ExtractContent function.

The wording, although a bit confusing (ExtractContent is a method, non a function), seems to suggest that something like this is possible:

	b, err := objects.Download(client, "container", "object", nil).ExtractContent()
	if err != nil {
		panic(err)
	}
	fmt.Printf("---\n%s\n---\n", b)

However, this doesn't work because the result of Download is a bare DownloadResult value, while ExtractContent is a method with a pointer receiver.

What is the recommended way to use ExtractContent?
