count.count

Sometimes you pick a programming idiom because it is what you are familiar with, because you think it is expected, or because it expresses clearly what the code you are writing is trying to do. Other times, it is just too hard to resist. Lately at work at least two of us have seen .count.count in our rails3 code, and at first were sure it must be a typo. The real story is more fun than that, see the nerdfeed blog for more.
