No, no, NO! See, this situation is exactly why I *wouldn't* want
Ruby's nil to follow the NilObject pattern (or whatever it's called).
If it did, Mark would be getting wrong results as opposed to the
undefined method exception. Which do you think is easier to debug?
I'll take the exception that tells me what line number, any day.
