This is such a great story and an important one. I always optimise examples for people copying and pasting, trying to make it as safe and meaningful by default as possible. It doesn't matter why you're copying and pasting - you may not have a lot of skills in this specific area, or you might be in a hurry. If you know what you're doing, you can probably improve the code, but if you use it as-is, it shouldn't come back to bite you!
