in reply to why use a hash instead of an array

Others have touched on many of the ways that hashes are useful. I'll just add that, when I have a list of values, often I'll make them the keys of a hash right from the start, rather than putting them in an array, because there's a good chance I'll need them in a hash at some later point.
