> So... imagine that someone enters a kitchen, because they want to show you how to make a cup of coffee. As you watch carefully, they flick a switch on the wall. The switch looks like a light switch, but none of the lights in the kitchen turn on or off. Next, they open a cabinet and take down a mug, set it on the worktop, and then tap it twice with a teaspoon. They wait for thirty seconds, and finally they reach behind the refrigerator, where you can't see, and pull out a different mug, this one full of fresh coffee.
> ...What just happened? What was flicking the switch for? Was tapping the empty mug part of the procedure? Where did the coffee come from?
> That's what this code is like.
I hope to never write code that warrants a description half as scathing as this one
