in thread using ref to hash of hash effectively

I hope that we all can agree that when it comes to style issues, we should each be consistent. When one of these issues arises, we should form a standard which we are comfortable with and always use it.

In this case, I like the standard suggested by eyepopslikeamosquito. For my own use, I have added another rule. "No map or grep block should produce any side effects."
