Think of the array of elements as the first variable passed to the method. You can have three or more elements in that array, if that's how deep the nesting goes. But the array itself is the first variable, and in that limited way of looking at this, means that the documentation is correct to a point. I agree, it would be good if there was a signature showing this in the API docs. Good thing that Rails is open source -- you can get a commit out of this if you write it up and submit a pull request on GitHub!
