Indeed, you are right and I am wrong.

Perhaps https://golang.org/pkg/net/http/#Server is a better example.
There is e.g. a ReadTimeout exported field (amongst many configuration
parameters), but there is no http.NewServer function, let alone one
that takes all of the various config params. Instead, as the Overview
section of https://golang.org/pkg/net/http/ says:

```
More control over the server's behavior is available by creating a
custom Server:

s := &http.Server{
Addr:           ":8080",
Handler:        myHandler,
ReadTimeout:    10 * time.Second,
WriteTimeout:   10 * time.Second,
MaxHeaderBytes: 1 << 20,
}
log.Fatal(s.ListenAndServe())
```
