@steveklabnik likes to have examples attached to every function, and this does show how to use new. Even if it duplicates other examples used for other purposes it may still be valuable.

I think there isn't enough value providing examples for new(), especially if they don't even take arguments. Failing that, would it be enough to remove the last line in the example since it's demonstrating something else?

[steveklabnik]

Don't underestimate how important examples, even the simplest, are to people getting started. Yes, it's not particularly exciting, but it is valuable.

That's why the last line matters, it's an example of how to use new to accomplish the task you've set out to do: actually open a thing.

I can sort of see removing the last line. Not every example has only the exact thing it's showing off; they often show how they interact with other bits of the API.
