Actually, it's funnier than that: I now notice that the code I swiped from
you passes the original arrays, not even the "copies" which aren't copies.
That's what I meant to do: make a copy when I wrote chute_nums = chutes. So
I should have passed chute_nums to summarize_game, but it still wouldn't
work (because it's not a copy). More below.
