Thanks, Nathan. The line above caught my eye. It's interesting to see
that you don't need both 'push' and 'split' to populate the hash.
Could you explain a little about what the square brackets are for here?
Does that have something to do with array ref's? Sorry... hashes are a weak
spot of mine.
I also noticed that you wrote the split as
> (split /,/ => $zipcodes)
instead of
> split (/,/ => $zipcodes)
Is that just a stylistic difference or is there something more to it? Both
work for me.
