Unwanted Surprises

There is the higher-order question of whether loosely typed languages with coercion are really a good idea in the first place. If you don't know what you're operating on, or what the expected output range might be, then maybe you ought not to be operating on that data in the first place. But now these languages have gotten into the wild and we'll never be able to hunt them down and kill them soon enough for my liking, or for the greater good.
