This is perfectly valid --- just want to show one way to get values out of a hash. I'm not sure I'd even use it here, but when you need to extract values out of an arguments hash inside a method, this is pretty cool:

```ruby
time, message, execution_time = params.values_at("time", "msg", "exec_time")
LogRequest.log_request time, message, execution_time
```

Here's a simple example: http://rubyfiddle.com/riddles/e78d5
