All, please ignore this. I revisited my intial assumptions (that all names in the original data were unique!) and discovered that perl, since it's so smart, is correct. Since hash keys automagically take care of duplicates (behavior that I'm relying on when analysis kicks in later!), they disappear in the hash but remain in the file.
Please return to your regularly scheduled programming.
