Part of the beauty of `run` is that you don't have to declare and name a function `calcX`. In longer and more complex examples, declaring a function inline like this is potentially confusing because you don't get to see where it is used, whereas with `run` you assign the return value immediately to a variable.

It only exists in the scope of the parent function, the only place it can be used is right next to where is declared. Unless you're in the habit of making functions hundreds of lines long, I guess...
