On the contrary, you're sorting the keys of the hash, but you lost the order of the input. Given the sample data I used in my script (one foo bar one baz two quack baz) the sort method prints out bar, baz, one, quack, foo, two
. Of course if one wanted the sorted order then the use of the array is pointless. But if one is looking for the order of the input data, an array (or a module) is, as far as I know, necessary.
