Well, for me, it is a good point. For some reason it's just much easier for me to remember a particular language's way of doing something when there's only one way.

Also, I'm a little obsessive about my code consistency, so I dislike having to remember that I've been using Array#size instead of Array#length, for instance.

Now, these are obviously not necessarily applicable to anyone else. However, I do feel like I can say that having only one way to do simple things is a plus, without being a "religious nutjob". Which is kind of inflammatory of you to say, by the way.
