Personally, I'd expand this example to include the full HTTP example, just so `request` can be given a type.

So like:

```go
http.HandleFunc("/foo", func(w http.ResponseWriter, req *http.Request) {
        file, err := os.Open("filename.ext")
        if err != nil {
                yeller.NotifyHTTP(err, req)
                yeller.NotifyHTTPInfo(err, ...)
                log.Fatal(err)
        }
})
```
